Blink and you miss it. That is the truth about the fastest UFC knockouts on record. Fights are meant to be three rounds long, or five if it is the main event, but the men on this list needed less time than it takes to tie your shoelaces.
None of these finishes were flukes either. That is the bit most people miss. When you dig into the coach interviews after the fact, you find out the same thing every time. The technique was drilled. The read was planned. The fighter walked out to the cage knowing precisely what he was going to throw and roughly when he wanted to throw it. What separates them from the rest of the roster is not the punch or the kick itself. It is the confidence to actually pull the trigger when the referee waves the fight on.
Below you will find the top ten fastest KOs in UFC history, ranked using the official UFC record book. Each entry breaks down the fight, the finish and the man who pulled it off. For the odds on the next big card, head over to our full UFC 329 McGregor vs Holloway 2 preview.
1. Jorge Masvidal KO Ben Askren – 5 seconds (UFC 239)
This one is the daddy. Nothing else comes close. Ben Askren rocked up to the T-Mobile Arena on 6 July 2019 sitting on a 19-0 professional record, having already ruled ONE Championship and Bellator at welterweight and freshly plucked into the UFC roster in a big-money trade. He was the favourite. The buildup had been ugly. Askren had spent months winding Masvidal up on Twitter, and Masvidal had made no secret of what he thought about that.
Then the bell rang. Masvidal did not wait. He sprinted straight across the cage, jumped, and buried a flying right knee into the side of Askren’s head just as Askren dropped his level for a takedown. Askren was already out cold when he hit the mat. Referee Jason Herzog let two ground shots go before waving it off, and the clock stopped at exactly five seconds. Turns out Masvidal had been drilling that entry with striking coach Paulino Hernandez all camp. It set a UFC record that has stood for the best part of seven years, it made Masvidal a household name overnight, and it earned him the BMF title fight against Nate Diaz later that same year. Askren, for his part, quietly retired before the end of 2019.
2. Duane Ludwig KO Jonathan Goulet – 6 seconds (UFC Fight Night 3)
Before Masvidal, this was the record. And it held for 13 years. Duane “Bang” Ludwig walked into a welterweight bout with Jonathan Goulet at UFC Fight Night 3 on 16 January 2006, took a couple of steps toward the middle of the cage, faked a low kick, and dropped Goulet clean with a short straight left. Fight over.
The funny bit is the finish was originally recorded at 11 seconds due to a timekeeping error. It took the UFC years to go back through the footage and formally correct it to six. Ludwig has since become one of the most respected striking coaches in the sport, running his own gym in Colorado and famously guiding TJ Dillashaw to the bantamweight title. Not bad for a man whose own record moment was almost lost to a broken clock.
3. Todd Duffee KO Tim Hague – 7 seconds (UFC 102)
Fastest heavyweight KO in UFC history, and the moment Todd Duffee looked like he might be the next big thing. Duffee took on Tim Hague at UFC 102 on 29 August 2009 in Portland. He walked forward from the whistle, cracked Hague with a lead uppercut and finished the exchange with a right hand behind the ear. Hague was flat on his back at the seven-second mark.
Duffee was tipped as a future title contender off the back of that finish. It did not quite pan out. Less than a year later, he lost to Mike Russow in a fight he had been winning until the third round, and the UFC cut him shortly afterwards. Even so, the Hague KO remains the quickest heavyweight finish anyone has managed inside a major promotion.
4. Chan Sung Jung KO Mark Hominick – 7 seconds (UFC 140)
The Korean Zombie at his brutal best. Chan Sung Jung was up against Mark Hominick at UFC 140 in Toronto on 10 December 2011 in a featherweight bout, and had already earned himself Fight of the Night honours in his previous UFC outing against Leonard Garcia. His whole style was built on forward pressure, which is not typically the kind of style that produces seven-second finishes. As anyone who has read our UFC scoring system guide will know, dominant control tends to bank the rounds. This fight went nowhere near the judges.
Jung sprinted forward, threw a jab that Hominick reacted to, and slipped a short right hand around the outside of his guard that landed square behind the ear. Two hammer fists on the ground later, and it was done. Seven seconds. The Korean Zombie carried that moment across the rest of a decorated career, eventually retiring in 2023 as one of the most-loved fighters ever to grace the featherweight division.
5. Ryan Jimmo KO Anthony Perosh – 7 seconds (UFC 149)
If there is a UFC debut more emphatic than Ryan Jimmo’s, we would love to hear about it. Jimmo, a Canadian light heavyweight, made his first UFC appearance at UFC 149 in Calgary on 21 July 2012. He walked forward, dropped a chopping overhand right on the ear of Anthony Perosh, and by the time the ref got there Perosh had already taken two follow-up shots on the ground. Seven seconds.
The bit that made the internet was what happened next. Jimmo, still standing in the middle of the cage, launched into a full robotic dance celebration. It became one of the most-replayed clips of the year. Jimmo hung around the UFC for another three years before being released in 2015, and tragically died in 2016. The Perosh finish is how most fans remember him.
6. Terrance McKinney KO Matt Frevola – 7 seconds (UFC 263)
The newest name in the seven-second club, and one of the most chaotic UFC debuts of the last five years. Terrance McKinney was up against veteran lightweight Matt Frevola at UFC 263 in Glendale on 12 June 2021. He came out swinging, landed a lead right hand that put Frevola on the canvas, and closed the fight out with a flurry of elbows and hammer fists.
And then McKinney celebrated by attempting a backflip, which he landed successfully, and simultaneously tore his own ACL. That is the sort of debut that gets remembered. He picked up the record for the fastest UFC finish and one of the daftest post-fight injuries in the sport’s history in the same 30-second window. McKinney has since built out a proper UFC career at 155, but nothing quite tops the way it started.
7. James Irvin KO Houston Alexander – 8 seconds (UFC Fight Night: Florian vs Lauzon)
James “The Sandman” Irvin earned his nickname on 2 April 2008 in Broomfield. Standing across the cage from Houston Alexander, a man with legitimate one-punch power, Irvin threw a superman punch from a range that did not look possible. Alexander did not see it coming. He fell face first, and referee Herb Dean was already waving it off before he made a second attempt to get up.
The finish came in at eight seconds and remains the quickest superman punch KO in UFC history. Some at ringside genuinely missed the moment of impact. It goes by that quickly.
8. Makwan Amirkhani KO Andy Ogle – 8 seconds (UFC on FOX: Gustafsson vs Johnson)
Finnish featherweight Makwan Amirkhani arrived in the UFC with an absolute banger. He took on Andy Ogle at UFC on FOX in Stockholm on 24 January 2015, ran at him from the opening bell, and buried a flying knee into Ogle’s chin. A handful of ground shots followed and the fight was called at eight seconds.
Amirkhani has been on the UFC roster for over a decade now and is one of the most recognisable European featherweights in the promotion. The Ogle finish is still the one people talk about.
9. Leon Edwards KO Seth Baczynski – 8 seconds (UFC Fight Night: Gonzaga vs Cro Cop 2)
Now this one hits close to home. Birmingham’s Leon Edwards was 23 years old, still finding his feet on the European circuit, when he took on the seasoned American Seth Baczynski at UFC Fight Night in Krakow on 11 April 2015. He threw a jab. He feinted a cross. And then he uncorked a left head kick that put Baczynski down at the eight-second mark. This was years before Edwards would become a permanent fixture near the top of the UFC welterweight division, but the finish told you everything you needed to know about where he was heading.
Fast forward seven years. Edwards is losing on the scorecards against Kamaru Usman in the fifth round at UFC 278. He has less than a minute left in a fight he needs to finish, throws the exact same left head kick, this time with a title on the line, and produces the “Head Shot Dead” moment that will define British MMA for a generation. He held the belt through three defences before losing it to Belal Muhammad in July 2024.
The Baczynski KO is worth going back and watching just to see how early Edwards trusted that kick. Everything he became was already there in the eight seconds it took him to finish Baczynski.
10. Abdul Rakhman Yakhyaev KO Julius Walker – 8 seconds (UFC Fight Night: Fiziev vs Torres)
The newest name on this list. Dagestani lightweight Abdul Rakhman Yakhyaev made his UFC debut at UFC Fight Night: Fiziev vs Torres on 27 June 2026, less than a week ago as of writing. He walked out looking every bit the American Kickboxing Academy product he is, feinted the takedown that Walker was clearly bracing for, and cracked him with a straight right hand over the top. Eight seconds.
Yakhyaev is the first debut fighter to break into the eight-second club since Amirkhani did it more than a decade ago. Worth keeping an eye on how his UFC run develops.
What Makes a Fast UFC Finish Possible?
Look at every entry on this list and you will spot the same pattern. The winning fighter had one specific technique burned into muscle memory, and the guts to fire it before the fight had even settled into a rhythm. Masvidal’s flying knee. Edwards’s head kick. The Korean Zombie’s short right behind the ear. None of it happened by accident. They were plays. Rehearsed plays, executed with genuinely elite timing. To put that in perspective, remember that the full three-round UFC fight lasts 15 minutes. A five-second finish uses less than 0.6% of the total available fight time. Everything else in the fighter’s toolbox becomes irrelevant.
The other thing worth mentioning is the loser in every one of these fights. Look who was on the receiving end. Askren was a wrestler. Perosh was a jiu-jitsu specialist. Baczynski was known for being tough as boots and expected to wade forward and walk Edwards down. The pattern is not accidental. Every man who lost inside 10 seconds was expected to survive the opening exchange and impose his own game plan afterwards. None of them got the chance.
KO/TKO Betting on UFC Fights
From a betting angle, this stuff matters. Method of Victory KO/TKO markets tend to offer significantly better value than the moneyline whenever a striker is up against a wrestler or a grappler, and that value multiplies in the first round. Fighters with a genuine, documented pattern of finishing inside the first minute represent some of the sharpest KO/TKO plays across the calendar year. And unlike submission finishes, a fast KO does not need positional control or ground specialism. All it needs is one clean shot.
Round-specific markets sharpen that angle even further. A KO/TKO in Round 1 line on a fighter who consistently finishes in the opening minute can pay several times the outright moneyline. Add Method plus Round to the mix and you are compounding two variables at once, which is where the really long odds start living. It takes conviction to bet the exact round, but the payoff when it lands is very often the difference between a decent night and a memorable one.
