5 Most Brutal MMA Knockouts

#3 Cain Velasquez vs. Junior Dos Santos 3

The Cain Velasquez-Junior Dos Santos series of fights is perhaps one of the most talked-about trilogies in the UFC.

The first fight witnessed JDS annihilate Velasquez with a beautiful overhand right, which landed behind the latter’s ear and rattled his equilibrium instantly. While JDS won that fight by KO, Velasquez successfully defeated Dos Santos in the rematch—by way of a dominant 5-round decision victory.

The second fight saw JDS sustain an ungodly amount of punishment, and although he managed to survive till the final bell, experts noted that the prolonged beating he sustained at the hands of Velasquez may have changed Dos Santos forever.

The aforementioned prediction proved to be true, as JDS seemed noticeably slower in his trilogy matchup against Velasquez at UFC 166. Velasquez laid an even more brutal beating on Dos Santos in their third fight—stopping Dos Santos in the fifth and final round of their matchup with a violent slam and follow-up punches.
