Top 25 UFC Knockouts Since 2015

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.
