Top 25 UFC Knockouts Since 2015

10. Lando Vannata vs. John Makdessi

Entertainment follows Vannata like a rat behind the Pied Piper. He has never delivered on his promise to be a contender, but he is one of the most exciting action fighters on the roster. Vannata’s most stunning highlight reel moment came at UFC 206 when he crushed Makdessi with a beautiful spinning roundhouse kick. It was both sickening and stunning.

The opening of this fight was cagey but Vannata slowly took over. He moved Makdessi backward and connected with a leg kick first. Makdessi fell like a tree after the follow-up spinning roundhouse kick reverberated off of his head. His heel smacked off of Makdessi’s head as if it were a sledgehammer. It was one of the best knockouts of 2016.

9. Kevin Lee vs. Gregor Gillespie

Lee is one of the most frustrating fighters in MMA. The Detroit native has all of the athletic gifts but often lacks the tactical nuance against high-level athletes. However, he has provided some superb moments. His most notable KO victory came against Gillespie when he landed a crushing head kick to win the fight. He crashed to the ground with a sickening thud.

After going back-and-forth for most of the round, Lee threw two punches with a rear-leg roundhouse close behind them. He connected with ‘The Gift’s’ temple, sending him to sleep immediately. Gillespie lay on the floor motionless for a few minutes before he finally came to his senses. As savage head kicks go, this one was brutal and terrifying in equal measure.

8. Cody Garbrandt vs. Raphael Assuncao

After three straight defeats by KO, Garbrandt came back strong. The former UFC bantamweight champion looked like he was on track to be a superstar but a disappointing fight IQ cost him badly in the cage. He faced veteran Assuncao at UFC 250 and knew that this was his final opportunity to stay relevant. In the end, he stole the show with a devastating finish.

It came at the end of the first round of their fight. Assuncao threw a strike, but ‘No-Love’ ducked underneath and swung a fearsome overhand to crush his Brazilian opponent. Assuncao crashed to the ground like a fallen tree. It was spectacular, clinical, and devastating from Garbrandt and one of the best knockouts of 2020, all with one second left in the round.

7. Stipe Miocic vs. Fabricio Werdum

Going to Brazil is always one of the most intimidating atmospheres in MMA for foreign fighters. However, UFC heavyweight challenger Miocic didn’t allow it to overwhelm him when he faced the champion Werdum in Curitiba. In fact, this was the first stunning victory on his road to officially becoming the greatest UFC heavyweight champion of all-time.

Werdum advanced forwards towards Miocic at about the midway point of the round. The American continued to throw punches as he moved backward despite severe pressure. He managed to connect with the Brazilian’s chin and put him to sleep in style. It was one of the most satisfying knockouts on this list and a reminder of what heavyweights can do at any time.

6. Joaquin Buckley vs. Impa Kasanganay

Immediately billed as the greatest knockout in UFC history, we’re not going to give it that status. It loses out on jeopardy points because it came in the prelims of UFC Fight Island 5 in Abu Dhabi in 2020. Buckley vs. Kasanganay was a very even fight until the finish came in the second round. When it arrived, nobody could believe what they just saw because Buckley produced a moment of epic brutality.

Buckley threw a kick which Kasanganay caught. But then, with one foot still in Kasanganay’s hand, Buckley spun and landed a ridiculous jumping back kick to his opponent’s chin. He went out like a light and hit the mat as his eyes rolled back in his head. Instantly, Buckley made a name for himself with a dynamic and creative KO. Do you think it deserves to be higher up this list?

5. Conor McGregor vs. Jose Aldo

Some will cry this doesn’t deserve to make our top five, but that totally removes the context of the situation. After one of the biggest buildups in the history of the sport, unbeaten featherweight champion Aldo faced off against upstart challenger, McGregor at UFC 194. ‘The Notorious’ played mind-games before the fight and promised to knock him out in the first round.

Aldo rushed in from the start and McGregor immediately countered with a stunning 13-second finish. Nobody could believe what they had just seen. It was the quickest knockout in UFC title fight history. The drama, excitement, and efficiency of this finish make it one of the most infamous ever. Nobody knew if McGregor could do it but he did.

4. Jessica Andrade vs. Rose Namajunas

Namajunas put on the performance of her life against Andrade. At least, until the Brazilian slammed her on her head. ‘Thug Rose’ was the strawweight champion and demonstrated some beautiful movement and slick striking against her challenger. It looked like she was on a different level to Andrade. However, the Brazilian had a trick up her sleeve.

The finish came about three minutes into the second round. As the pair moved into the clinch, Namajunas took a risk and attempted a flying armbar. Andrade used her opponent’s momentum against her to smash her head-first into the ground. It was a sickening KO as Namajunas’s head bounced off the mat. Andrade became the new champion in savage style.

3. Francis Ngannou vs. Alistair Overeem

This was the night that Francis Ngannou arrived. He fought against former DREAM, PRIDE, and K-1 champion Overeem in the co-main event of UFC 218. There are some spectacular knockouts on this list but none of them made us actually fear for the victim’s life like this one did. ‘The Predator’ demonstrated devastating raw power as he sent Overeem into the next world.

Ngannou landed a ferocious uppercut that snapped Overeem’s neck back to a disgusting angle. The power and explosiveness of the Cameroonian fighter made him instantly the most feared fighter on the entire roster. Remarkably, Overeem recovered but he probably doesn’t remember much about it. It was definitely one of the most terrifying of all-time.

2. Jorge Masvidal vs. Ben Askren

There was bad blood coming into this one. Askren rode the hype train into UFC 239 against Masvidal. The former ONE and Bellator champion was also a champion trash-talker. But he didn’t realize that his opponent was plotting his demise in the most brutal fashion. Finally, the pair faced off across from each other in the octagon. However, it didn’t last long.

Askren moved forward with his hands down, clearly looking for a takedown. Masvidal fully expected this. He charged across the cage and landed a stunning flying knee. It was the fastest knockout in UFC history at just five seconds. Even though, Askren was out for the count, ‘Gamebred’ still followed up with a couple of heavy hammer-fists. According to the Cuban-American, they were ‘super necessary.’

1. Yair Rodriguez vs. Korean Zombie

Chan Sung Jung was literally about to win this fight before Rodriguez stunned the world. Their clash took place in the main event of a UFC Fight Night in Denver, Colorado. Both men had their moments throughout the fight. But the Korean Zombie’s compact boxing style had the edge over Rodriguez’s flashy, kick-heavy style. But then suddenly it ended.

With a single second left on the clock, Zombie moved forward aggressively. His Mexican opponent sprung a back-upward elbow that connected perfectly with the Korean’s chin. He went down like a sack of coal and Rodriguez won the fight. In sum, this was arguably the greatest UFC knockout of all-time. The last-second drama and the spectacular nature of the finish make it iconic.
