5 most vicious Derrick Lewis KOs in the UFC

#4. Derrick Lewis vs. Aleksei Oleinik - UFC Vegas 6

In August 2020, Derrick Lewis squared off against submission specialist and MMA veteran Aleksei Oleinik in the main event of UFC Vegas 6.

Oleinik is arguably the most dangerous grappler in the history of the UFC heavyweight division. His gameplan in the fight against Lewis was clear as day – to take 'The Black Beast' down and choke him out.

Oleinik secured a takedown in the very first round and controlled top position for several minutes. However, he wasn't able to find the finish. In the second round, the Russian tried to take Lewis down once again, but this time the Houston native saw it coming.

He threw a powerful flying knee at Oleinik, forcing him to back away. As he did separate, Lewis landed a powerful right hook that saw his Russian counterpart crumble to the canvas. After a few extra follow-up shots, the referee stopped the fight.

#3. Derrick Lewis vs. Travis Browne - UFC Fight Night 105

Heavyweight contenders Derrick Lewis and Travis Browne locked horns in the main event of UFC Fight Night 105 in February 2017. Both top-ranked fighters were looking to move one step closer to a title shot and an opportunity to take on then-champion Stipe Miocic.

The heavyweight duo put on a barnburner of a fight that ended up winning the 'Fight of the Night' honor. Lewis and Browne went back-and-forth in the first round and somehow managed to make it through the opening five minutes.

In the second round, Browne started to attack Lewis' body. The damage was seemingly mounting as 'The Black Beast' started to drop his hands in anticipation of the incoming body shots.

As Browne attempted another body kick, Lewis threw a powerful hook that landed on the former's forehead. He crashed down to the mat and a few ground strikes later, referee Mario Yamasaki stopped the fight.
