Top 10 Most Disappointing Fights in UFC History

The massive fight between 19-0 middleweight champion Israel Adesanya and 13-0 top contender Paulo Costa is just days away and the MMA world is justifiably amped up for the tantilizing title fight.

It's just the second UFC men's title fight to pit two undefeated fighters against one another and although Israel Adesanya is coming off a career-low performance (or lack thereof) against Yoel Romero in his last middleweight title "defense", given Costa's unrelenting pressure and fearless aggression there is little chance that the fight isn't entertaining for as long as it lasts.

As I wrote those words however, I'm reminded of how excited I, like all MMA fans, was prior to Adesanya's last bout, which got me thinking about other disappointing fights in UFC history.

Rather than just picking the worst fights in UFC history, of which bouts between fighters with subpar skills would feature most prominently, instead this list deals with pure disappointment - these are fights that fans were extremely excited about that ended up failing to live up to the hype, even if they weren't neccessarily the worst bouts when viewed without context.

So without further ado, here are the top ten most disappointing fights in UFC history.

10. Frank Mir vs. Mirko Cro Cop

UFC 119, September 25 2010

Heavyweight MMA has followed a pretty clear algorithm since the beginning of the sport - if the fight doesn't end in a finish within the opening round, it's likely going to be an absolute chore to sit through.

There are occasional exceptions to the rule, mostly when the few truly elite heavyweights enter the cage or ring, but for the most part, if a heavyweight fight passes the five minute mark you're unlikely to be entertained save for a random finish that puts an end to the sloppy scrap.

Originally scheduled to face Antonio Rodrigo Nogueira for the second time, Frank Mir instead saw himself take on a replacement in another PRIDE heavyweight legend, Mirko Cro Cop at UFC 119.

It may not have been the strongest PPV card ever, but it was headlined by two legends with massive name value that, although neither was considered in their "prime" anymore, were both regularly exciting.

The former UFC heavyweight champion Mir was coming off a brutal loss at the monstrous hands of Shane Carwin and was looking to bounce back after once again getting mauled by a bigger, stronger athlete, his 72-second shellacking of Cheick Kongo sandwiched between tough losses to Brock Lesnar and the afforementioned Carwin.

While he may not have had a lot of momentum, Mir could always be counted on to deliver a quick and exciting fight - the only time he had ever even seen a third round was a fight back in 2006 when Mir had returned following a devastating leg injury and was in horrendous shape - all of his other bouts, win or lose, ended in a finish within two rounds (often within two minutes) whether it be via knockout or from one of his legendary, bone-breaking submissions.

Mirko Cro Cop on the other hand was seemingly in the midst of one of his career resurgences, having won four of his last five fights (all by form of finish). His recent wins included an epic kickboxing battle with Pat Barry and his lone loss came at the hands of future heavyweight champion Junior Dos Santos thanks to a broken orbital bone.

The PRIDE legend's resume truly spoke for itself and he always delivered action for the fans.

Mirko was one of the rare breed of athletic heavyweights that could still fight well even a round or two into a bout, and of course his highlight reel of knockouts was legendary for a reason - whether he was head kicking Igor Vovchanchyn, Alexander Emilianenko, and Wanderlei Silva, smashing the likes of Mark Coleman and Josh Barnett with his fists, or engaging Fedor Emilianenko in what many regard as the greatest fight of the prior decade, the Croatian kickboxer was always a special treat to watch perform.

And then the main event of UFC 119 happened.

Mir looked in better shape than his last two outings, where he had beefed up his frame to almost comical levels that as a result left him nearly immobile, showing off solid defense when Mirko opened up in the early seconds.

And then little else happened for over 13 minutes.

Both men seemed to respect the power the other possessed and as such appeared extremely timid, each hoping for the other man to make a costly mistake and refusing to be the one to go first.

Mir's attempts to take the fight to the mat were unsuccessful thanks to his rather lackluster wrestling and Cro Cop's excellent takedown defense, leaving the two heavyweights in the clinch for extended periods where neither man did much of anything. At range, it was essentially a staring contest.

The crowd quickly lost their patience, showering the two legends with boos as the minutes ticked by. Somehow, despite the tepid pace and his utter lack of output, Mir was breathing heavy and appeared to be tired (it was a heavyweight fight that made it past the first round after all), though Mirko did little to exploit it.

With about two minutes left in the three-round main event, fans had already started pouring out the exits, annoyed they had stuck around for such a disappointing headlining act.

And then with about one minute left in the fight, Cro Cop pressed the action and looked to land his left hand out of a clinch; instead, pulling Mirko's head down via a single collar tie, Mir delivered a vicious knee to Cro Cop's chin that sent the legend crashing to the canvas.

It was a brutal knockout that did little to make up for the previous fourteen minutes of inaction, and in fact made it an even sadder outcome for those in attendance (at least the ones that were still in the arena) - seeing the aging warrior knocked dead in the dying seconds of a horribly boring fight was not what anyone was hoping to see.

9. Ken Shamrock vs. Dan Severn II

UFC 9, May 17 1996

If you asked a few UFC fans that have been following the sport since its early days what the worst UFC main event of all time was, odds are at least one of them will bring up Ken Shamrock vs. Dan Severn II.

Back in the very early days of the UFC, individual match-ups didn't have a lot of build-up thanks to the tournament format, but the advent of a "Superfight Championship" starting at UFC 5 changed that and added a more boxing-esque quality to the promotion courtesy of non-tournament bouts between two established names headlining an event and drawing in viewers.

Ken Shamrock, an early star in the sport as well as in pro wrestling who had lost to Royce Gracie at UFC 1 and made it to the finals of UFC 3 before an injury saw him withdraw from the tournament, took part in the very first "Superfight" in MMA history - a rematch between himself and the winner of UFC 1, 2, and 4 (and similarly a competitor at UFC 3 who withdrew due to injury), Royce Gracie.

After a draw saw the new belt left undeclared and Gracie leaving the sport for a while, Shamrock was given a second crack at the "Superfight" title against the runner-up of UFC 4 and the winner of UFC 5, Dan Severn.

This time Shamrock would emerge victorious in just over two minutes via a guillotine choke in a fun scrap which included Severn hitting a beautiful suplex early on.

Shamrock would fight to another draw in his next Superfight against Oleg Taktarov before tapping out Kimo Leopoldo in his next outing; Severn on the other hand would become just the second man to win multiple UFC tournaments by winning the "Ultimate Ultimate 1995" event, earning himself a rematch with Shamrock.

The Superfight at UFC 9 captured the attention of the early MMA world and fans were expecting another exciting scrap between the two, but unfortunately legal problems would end up turning the highly anticipated match-up into one of the most bizarre and terrible fights in UFC history.

Taking place in Detroit, Michigan and dealing with mounting political and media pressure given the sport's early reputation as "human cockfighting", the UFC's owners were stuck in a battle in the courtroom as lawmakers in Detroit moved to stop the event from taking place just days before the event.

At the eleventh hour, the event was allowed to go on but with some rather restrictive new rules in place - including the complete banning of strikes to the head with either closed fists or headbutts, with the Michigan Athletic Commission promising to arrest any fighter who violated these rules.

To make matters worse, kicks were also banned if the fighters decided to wear shoes for their bouts. Given that both Shamrock and Severn were wrestlers, both opted to lace up their wrestling shoes and as a result limited their offensive arsenal even further.

Now a bout with those kind of crippling restrictions (especially on such late notice) is sure to be a dud, but that's not something fans knew about before sitting down to watch the pay-per-view. What they were promised was a no-holds barred fight between two of the toughest fighters on the planet - what they got was one of the most disappointing "fights" they could imagine.

Surely wanting to avoid another submission loss, the superior wrestler Severn opted to avoid grappling for almost the entire 30-minute affair, instead choosing to engage with Shamrock in what amounted to a glorified staring contest.

For half an hour two of the "baddest men on the planet" gazed into each other's eyes and circled around the Octagon, occasionally throwing open handed slaps at each other before returning to their incredibly dull dance.

Near the end of the fight Severn finally had enough and took down Shamrock, landing a few strikes (closed fists to boot...luckily, he wasn't arrested) before the horn sounded and ultimately earned himself a decision "victory".

The fight was truly a product of its time and one can't help but feel extremely sorry for any poor sap that spent their hard-earned money back in 1996 on this travesty of a fight.

8. Vitor Belfort vs. Randy Couture II

UFC 46, January 31 2004

UFC 46 was a massive event at a time when the UFC was struggling to survive.

In addition to a highly anticipated rematch between Frank Mir and Wes Sims (the first fight saw Sims disqualified for illegally stomping on Mir's face, repeatedly and while grabbing the cage no less), the man everyone considered to be the best lightweight in the world was moving up to challenge longtime welterweight kingpin Matt Hughes for this throne. Even the prelims would prove memorable, with future GOAT Georges St. Pierre making his UFC debut that night.

To top off the impressive card, early UFC star Vitor Belfort would finally look to realize his potential as he sought to dethrone the light heavyweight champion Randy Couture, the former heavyweight champ and the man who handed Vitor Belfort the first loss of his career back at UFC 15.

Since Couture grounded and finished the young Brazilian phenom in 1997, "The Natural" had experienced both the highs and lows of the sport. Posting a record of 7-5 at heavyweight, Couture went on to capture and defend the UFC heavyweight title before subsequently losing it to Josh Barnett, who would later be stripped due to a failed drug test; Couture would then lose against Ricco Rodriguez in his attempt to reclaim the vacant title.

At 38 years of age, many wrote Randy off and expected the Olympian wrestler to retire or fade into obscurity. Instead, given his roughly 220lb frame which was tiny for a heavyweight, Couture opted to drop down to his natural weight class of light heavyweight.

Couture would be paired up with rising star Chuck Liddell for an interim championship given Tito Ortiz's reluctance to fight his "friend" Liddell, the interim belt on the line in the UFC's effort to force champion Ortiz into accepting a fight with "The Iceman". To everyone's surprise, Couture dominated Liddell en route to a third round TKO.

Randy would then decimate Tito Ortiz over the course of five rounds to emphatically capture the undisputed light heavyweight title, making him the first fighter in UFC history to capture undisputed titles in two different weight classes.

After having his air of invincibility shattered by Couture, Vitor would rebound with an easy submission win before scoring arguably the most famous knockout in the old days of the UFC - a 44-second blitzing of Wanderlei Silva during the UFC's first trip to Brazil that showcased the Phenom's incredible hand speed.

Belfort would then accept a lucrative offer from PRIDE, where he would post an impressive 4-1 record at heavyweight before the UFC lured him back stateside. Originally slated to fight Tito Ortiz for the title at UFC 33, injuries kept Vitor sidelined until he was matched up with the UFC's latest rising prospect in Chuck Liddell.

Belfort accounted well for himself in the fun 15-minute scrap but ended up losing a decision in his return to the Octagon, derailing his hopes for a title shot.

A year later he would return in emphatic fashion and remind everyone of his vicious finishing ability by absolutely trouncing Marvin Eastman, opening a disgustingly large cut over Marvin's right eyebrow that looked as if it were opened by a hatchet.

With Couture having already defeated Liddell and Ortiz, the stage was set for a massive rematch early in 2004 against the next top contender; would Couture's wrestling, dirty boxing and tactical brilliance get the job done once more, or would a more seasoned Belfort be able to realize his full potential and use his incredible athletic ability to earn himself the title and redemption?

Just as hype surrounding the bout was reaching a fever pitch, disaster struck as Vitor's sister Priscila went missing mere weeks before UFC 46.

As time went by it was suspected that she was kidnapped to be held for ransom given Belfort's status in Brazil, but the family received no ransom calls or other information, leaving what happened to her a mystery (in 2007 a woman admitted to her involvement in Priscila's botched kidnapping and murder, but her remains were never recovered from the supposed burial site leaving a definitive answer to her disappearance unknown to this day).

Despite the tragic circumstances, Belfort vowed to fight on and use the exposure of his fight to raise awareness for his missing sister, adding even more weight to the massive UFC 46 main event.

The rematch seven years in the making began with Couture closing the distance and looking to trap Vitor against the cage, with a left hand narrowly grazing him on the way in to the clinch. Vitor secured double underhooks and pinned Randy against the cage, only for the commentators (along with Vitor and shortly after the referee) to notice Randy wincing in pain and clearly having trouble with his eye.

Referee Big John McCarthy called a stop to the action and brought in a doctor, and it soon became clear that Vitor's left hook had grazed Couture's eye, the seam of his glove opening up a cut directly on Randy's eyelid.

Given the placement of the cut and the dangers it posed, the doctor called the fight and given the cut was caused by a punch and therefore a legal blow, Belfort was declared the winner.

While it was too short to be called a bad fight like many of the entries on this list, it was essentially no fight at all and answered exactly zero questions that fans had heading into the contest, ending what was otherwise a fantastic event on a down note even if seeing Vitor get the belt wrapped around his waist amidst all the turmoil he was going through was a touching moment.

7. Anderson Silva vs. Demian Maia

UFC 112, April 10 2010

Anderson "The Spider" Silva was at the height of his powers heading into the UFC's first ever trip to Abu Dhabi at UFC 112.

Having captured the middleweight title shortly after entering the UFC and defended the belt in dominant fashion five times already, as well as having two quick knockouts up at light heavyweight to his name and eight post-fight bonus awards in his ten Octagon appearances, the Spider was seen as an untouchable assassin designed to entertain the masses with his stellar defense, impressive Brazilian jiu-jitsu skills, and vicious Muay Thai.

His incredibly entertaining fighting style had recently given way to an incredibly frustrating and tiresome fight at UFC 97 however, where Anderson seemed content to play with his wildly overmatched foe for 25-minutes as renowned jiu-jitsu artist Thales Leites tried desperately to bring the fight to the floor and failed repeatedly, yet was hardly punished by the dominant champion.

The dismal performance drew the ire of the fans but his next outing quickly erased everyone's memory - moving up for another one-off fight at light heavyweight, Silva took on recent 205 pound champion Forrest Griffin at UFC 101.

The massively hyped fight had many believing the Spider may have bitten off more than he could chew given Griffin's size and highly underrated grappling abilities, but those beliefs were quickly silenced when the two entered the cage in Philadelphia.

Anderson danced around his lumbering foe as if he was in The Matrix, effortlessly dodging Griffin's strikes and landing precision counters in what can only be described as one of the most embarassing emasculations in UFC history. Griffin was dropped three times in the span of just over three minutes before the fight was stopped and to make matters worse, proceeded to run out of the cage following the fight.

The shocking dominance reminded the world what kind of otherworldly talent Anderson was and any memories of his tepid UFC 97 performance were immediately erased.

Slated to face off against Vitor Belfort early in 2010, an injury and a slower-than-expected recovery delayed the fight twice until April. Just weeks out from the UFC's historic trip to the Middle East, Vitor Belfort then injured his shoulder in training and was forced to pull out of his title shot; due to the next top challenger not being medically cleared to compete so soon after a recent bout, in stepped fellow Brazilian Demian Maia to save the day.

The 12-1 BJJ ace was easily one of the most accomplished Brazilian jiu-jitsu competitors to ever make the transition to MMA. Sporting a submission game unlike anyone in the sport, Maia had finished all but one of his wins and had already bounced back from his lone career defeat (a 21-second knockout loss) with a dominant decision victory.

Maia was certainly an interesting fighter and one to keep an eye on, but fans weren't exactly high on his prospects against the middleweight king heading into UFC 112.

Though his jiu-jitsu was otherworldly, his wrestling game had proven to be rather weak at the time and he held little chance of getting Silva down to the floor, especially on such short notice without having any time to really work on that aspect of his game.

Though he was learning the other aspects of the sport, Demian was a specialist through and through - his striking wasn't exactly what you'd call good, and considering he was going up against the best striker the UFC had ever seen, he was destined for an ass-kicking.

What virtually every fan had forgotten about was Silva's last fight against a man stylistically indentical to Maia.

Thales Leites was an extremely accomplished BJJ expert himself and also lacked much of a striking game at the time of his title shot at UFC 97. Despite being clearly outclassed by the Spider, he managed to survive 25-minutes without taking much damage simply by failing to get takedowns then proceeding to scoot around on his butt while Silva walked away or taunted him.

Given the heat Anderson had taken following that performance, and the adoration he had received for the brilliance he had put on display against Griffin, combined with the opportunity to showcase his talent to an entirely new market for the UFC's potentially lucrative new expansion? There was no way Silva would do something like that again.

But then he did.

Rather than dominating and finishing his clearly outgunned opponent on the feet, Silva effortlessly shucked off Maia's takedowns and attempts to pull guard, then proceeded to taunt him and run around the cage.

Occasionally throwing a hard leg kick or a bizarre strike amidst his taunts, Silva treated his massive main event gig as a playful sparring match. The entire fight was extremely frustrating for fans, especially given his abilities and that the co-main event had disappointed just before Silva made his walk; it was one thing for Silva to taunt his opponents, it was another to transform his entire performance into a circus act.

Now the fight would have featured even higher were it not for the fact that it had some funny moments and it's genuinely hilarious looking back at some of the ridiculous stuff Silva was doing in the middle of a UFC title fight, with absolutely no regard for the repercussions.

Whether he was standing still and begging Maia to hit him, backing Demian up with what looked like an epileptic dance routine, playing an air guitar, or trying to hide behind the ref, Silva dutifully played the part of a comedian at UFC 112.

Unfortunately for fans that had wanted to see a fight, Silva's performance was not a good one and it drew the wrath of Dana White, who promised Silva would never headline a card again (thankfully he didn't keep his word on that one) and said it was the most embarassing thing he'd seen in all his time in the sport.

Abu Dhabi didn't take too kindly too it either, with Silva's antics not going over well with the locals and damaging the brand in the region, with the UFC not returning to the Middle East for years following the debacle.

The very public backlash against his performance would have one assuming Silva learned his lesson, but he hasn't had to fight another BJJ specialist since, so we may never know if circus Silva truly died that night or he simply hasn't had a chance to return.

6. Derrick Lewis vs. Francis Ngannou

UFC 226, July 7 2018

If you were to ask a handful of MMA fans before UFC 226 what fight on the card was for sure not going to the judges' scorecards, the co-main event between Derrick Lewis and Francis Ngannou would have been the only answer you'd have received.

This was a match-up between two of the scariest and most vicious knockout artists in the heavyweight division, two massive (albeit with very different builds) power punchers that could fell a rhino with a single strike. While the superfight between heavyweight champ Stipe Miocic and light heavyweight king Daniel Cormier took top billing that night, the battle of the beasts was just as highly anticipated amongst fans and for good reason.

A developing standout from Cameroon, Francis Ngannou was a sizeable favourite heading into their massive clash at UFC 226. Despite coming off a loss in his title bid to Stipe Miocic, the "Predator" was still the most feared man in the division - his raw power and strength are second to none, and with the valuable experience he'd gained in his failed title shot he had undoubtedly become even more deadly.

After a decision loss in just his second pro fight, Ngannou tore through ten straight opponents, finishing all eleven of his career victories in ten minutes or less, with six of his victims coming in the Octagon. He had mauled Curtis Blaydes, smashed Andrei Arlovski, and positively murdered Alistair Overeem during his run for the heavyweight strap; in his highly anticipated title shot at UFC 220 however, Ngannou's inexperience cost him dearly as he discarded the patient counter-punching style that had gotten him there and instead went all out for the kill in the opening round.

Miocic being the savvy and durable champion that he is, weathered the early storm and stuck to a wrestling-heavy gameplan, wearing out his bigger foe and exposing Ngannou's weak grappling. Although he had little in terms of technique on the floor, Ngannou's athleticism and strength still allowed him to continuously get up off the canvas, Miocic forced to accept less dominant positions and patter away with light shots en route to a grinding decision victory.

Despite coming up short, Ngannou's raw ability was apparent and the Miocic fight served as a perfect learning experience for the developing fighter, particularly in teaching him that raw power alone isn't always enough.

On the other side of the Octagon would be the "Black Beast", Derrick Lewis.

Lewis is a gargantuan heavyweight with absolutely ridiculous power and explosiveness despite having a much less athletic (in appearance) figure than the likes of Ngannou. Lewis sported a 19-5 record having finished all but one of his opponents (the ridiculously durable Roy Nelson) and, save for two decision losses early in his career, all three of his more recent losses had come via form of knockout as well.

He was an honest-to-goodness brawler that could match Ngannou's size and punching power and wasn't afraid to throw his hands against anyone, as shown by his nasty knockouts over the likes of Guto Inocente, Gabriel Gonzaga, and Travis Browne.

The match-up had fireworks written all over it and as a result the fans were all up out of their seats when the two big hitters entered the cage...but what ensued was not what anyone had expected.

Rather than returning to his more patient approach and learning from his mistakes in the Stipe fight as most expected, Francis became a little too patient and instead was completely gunshy, unwilling to throw virtually anything at all.

Lewis on the other hand quickly picked up on his opponent's timidity and took advantage in the most conservative way possible, landing some leg kicks at a distance and throwing an occasional punch to do just enough to "win" the rounds on the scorecards without awakening the slumbering beast.

As a result one of the most boring 15-minute fights you'll ever witness went down inside the Octagon, virtually nothing of note occuring over its duration as Lewis cruised to an easy decision victory filled with lots of intense staring and little else.

The crowd voiced their displeasure throughout the tepid staring contest but to little avail - the two beasts just didn't show up that night and there was nothing they could do to change it.

Luckily both men would bounce back and return to form in their future fights, but that does little to erase the memory of one of the most uneventful fights in UFC history.

5. Tim Sylvia vs. Andrei Arlovski III

UFC 61, July 8 2006
