Fastest Knockouts in UFC History: Top 10 by Official Time

Event: UFC Fight Night: Fiziev vs. Torres, June 27, 2026, National Gymnastics Arena, Baku, Azerbaijan. Result: Yakhyaev def. Walker by KO (punches), Round 1, 0:08.

The newest entry. The undefeated Turkish light heavyweight walked across the cage, threw a right hand over Walker's lead shoulder before Walker had done anything, and the fight was over. A couple of follow-up punches on the floor and the referee waved it off at eight seconds.

It was the second-fastest finish in UFC light heavyweight history and moved Yakhyaev to 10-0 overall and 3-0 in the UFC. He is booked against Nikita Krylov at UFC 333 on October 24, 2026, in Abu Dhabi.

Event: UFC Fight Night 64, April 11, 2015, Krakow, Poland. Result: Edwards def. Baczynski by KO (punches), Round 1, 0:08.

Long before Rocky was head-kicking Kamaru Usman, he was a prospect on a Fight Pass prelim in Poland. Baczynski came out swinging, Edwards caught him clean as he charged in, and the follow-up punches on the ground ended it in eight seconds. It won him a Performance of the Night bonus.

Edwards went on to win the welterweight title at UFC 278 in August 2022 and defend it twice. He lost the belt to Belal Muhammad at UFC 304 in July 2024, then dropped fights to Sean Brady in March 2025 and Carlos Prates at UFC 322 in November 2025, the first knockout loss of his career.

Event: UFC on Fox 14, January 24, 2015, Stockholm, Sweden. Result: Amirkhani def. Ogle by TKO (flying knee and punches), Round 1, 0:08.

Mr. Finland's UFC debut lasted eight seconds. He charged out of the corner, launched a flying knee that caught Ogle clean, and finished him with punches on the mat. Performance of the Night in his first walk.

Amirkhani's UFC run ended in 2023 when his contract was not renewed. He fought in Oktagon in 2024, then moved to Ice Cage Fighting in Finland, where he won the lightweight title in 2025 with an anaconda choke. His record stands at 20-11.

Event: UFC Fight Night 13, April 2, 2008, Broomfield, Colorado. Result: Irvin def. Alexander by KO (punches), Round 1, 0:08.

Houston Alexander arrived in the UFC as a wrecking ball with brutal knockouts of his own. Irvin, the Sandman out of Southern California, made him the victim instead. A superman punch landed flush seconds in, and Irvin finished on the ground.

The knockout earned Irvin a $20,000 Knockout of the Night bonus. He fought until 2012 and later went into coaching in Rocklin, California.

Event: UFC 8, February 16, 1996, Bayamon, Puerto Rico. Result: Frye def. Ramirez by KO (punch), Round 1, 0:08, tournament quarterfinal.

The original. Frye was an Arizona State wrestler with a pro boxing background, and Ramirez was a 410-pound local. One right hand, eight seconds, and Frye had the fastest knockout in UFC history, a mark that stood until Ludwig and then Masvidal.

He was not done that night. Frye stopped Sam Adkins in the semis and submitted Gary Goodridge in the final to win the tournament. He entered the UFC Hall of Fame in 2016.

Event: UFC 263, June 12, 2021, Glendale, Arizona. Result: McKinney def. Frevola by KO (punches), Round 1, 0:07.

McKinney took the fight on short notice, eight days after a first-round knockout in LFA. He sprinted across the cage, dropped Frevola with a left hand, and it was over in seven seconds. It is the fastest finish in UFC lightweight history and the fastest debut finish the promotion has ever seen. He even tweaked his knee in the celebration.

The Spokane native is still on the roster. He stopped Kyle Nelson in 24 seconds in March 2026, then lost to King Green by TKO at UFC 329 in July 2026, which dropped him to 18-9.

Event: UFC 149, July 21, 2012, Calgary, Alberta. Result: Jimmo def. Perosh by KO (punch), Round 1, 0:07.

Jimmo made his UFC debut on home soil in Canada and needed one right hand. Perosh was out before he hit the floor, and Jimmo celebrated with the robot, which became his trademark. Knockout of the Night, 17-1 record, and a seven-second entry in the record book.

Jimmo died on June 26, 2016, in Edmonton after being struck by a truck following a parking lot altercation. The driver pleaded guilty to manslaughter and was sentenced to eight years in 2018.

Event: UFC 140, December 10, 2011, Toronto, Ontario. Result: Jung def. Hominick by KO (punches), Round 1, 0:07.

Hominick had just gone five rounds with Jose Aldo in Toronto. Seven months later, back in his home province, he lunged in with a wild right, ate a counter, and the Korean Zombie pounced. Seven seconds, Knockout of the Night and a $75,000 bonus.

Jung retired after a knockout loss to Max Holloway at UFC Singapore on August 26, 2023. He fought for the featherweight title twice and never won it.

Event: UFC 102, August 29, 2009, Rose Garden, Portland, Oregon. Result: Duffee def. Hague by KO (punches), Round 1, 0:07.

Duffee's UFC debut is still the fastest knockout in heavyweight history. He declined the glove touch, stepped in behind a jab, and a right hand put Hague down. A few more shots and the referee stopped it at seven seconds. Duffee was 6-0 and looked like the future of the division.

Injuries and layoffs wrecked that. Duffee's last recorded bout was a TKO loss to Ben Rothwell at BKFC Knucklemania IV in April 2024, and a scheduled 2025 bout was cancelled.

Event: UFC Fight Night 3, January 16, 2006, Las Vegas, Nevada. Result: Ludwig def. Goulet by KO (punch), Round 1, 0:06 per the UFC, 0:11 per the Nevada commission.

This is the asterisk. The timekeeper recorded 11 seconds, but the tape clearly shows Ludwig's right hand landing and the referee pulling him off around the six-second mark. In December 2011 Dana White told Ludwig he was being credited with the fastest knockout in UFC history, and the UFC posted a video timing the finish at 6.06 seconds.

The Nevada State Athletic Commission refused to change the result sheet, saying there was no legal avenue to do so. So the paper says 11 and the UFC says six. We go with the UFC here. Sherdog leaves him off its list entirely.

Event: UFC 239, July 6, 2019, T-Mobile Arena, Las Vegas, Nevada. Result: Masvidal def. Askren by KO (flying knee), Round 1, 0:05.

Askren was undefeated, a wrestling savant and a human megaphone. Masvidal read the shot before the bell finished ringing, sprinted across the Octagon and met Askren's takedown attempt with a flying knee. Askren was asleep on the way down. A couple of punches on the ground later it was over, and the official time was five seconds. Performance of the Night and a record that has now stood more than seven years.

That knockout made Gamebred a star. He beat Nate Diaz for the BMF title four months later, then lost four straight and retired after UFC 287 in April 2023 at 35-17. He boxed Diaz in July 2024 and has talked up a UFC comeback in 2026, but as of October 2026 he has not fought MMA since 2023. The record is still his.
