14 Epic Moments In The Undertaker And Brock Lesnar's 13 Year WWE Rivalry

6. Out-Of-Character Confrontation - UFC 121

Brock Lesnar must have been feeling pretty damn miserable following UFC 121, where he was easily defeated by Cain Velasquez in the main event. Cain won the fight in just 4.12 of the first round after battering The Beast Incarnate with a flurry of deadly punches. Lesnar had lost his UFC Heavyweight Title. Following the fight, Lesnar has a confrontation with noted UFC enthusiast The Undertaker. 'Taker was being interviewed by Ariel Helwani at ringside when Lesnar walked by, prompting the Undertaker to ask him 'you wanna do it?'. Lesnar just walked off and Undertaker refused to clarify the situation, saying 'it's personal'. The video was the talk of the wrestling world the next day, with some going as far as to speculate that Brock would be coming back to fight 'Taker at WrestleMania XXVII. Indeed, that was the plan all along, as the whole thing had been staged by the two men in order to drum-up interest in a potential match between them. That match never happened, as Dana White would never allow Lesnar to wrestle for WWE while he was under contract to the UFC.
