As we reported earlier, The Undertaker was in attendance at UFC 121: Lesnar vs. Velasquez last night and had an interesting exchange with former UFC heavyweight champion Brock Lesnar. Taker was being interviewed by MMAFighting.com's Ariel Helwani when Lesnar walked right by him. 'The Dead Man' asked Lesnar, "Do you want to do it?" Brock kept walking, not acknowledging his former rival.

When asked about the brief exchange, Undertaker admitted that it was personal but wouldn't go into specifics. Later, Helwani interviewed UFC President Dana White and asked him about the incident. Helwani noted that there were reports that WWE wants to do a Brock Lesnar - Undertaker match at WrestleMania, which may have been what Undertaker was alluding to when he asked, "Do you want to do it?"

White, who had earlier in the evening at the post-fight press conference stated that he and Lesnar had been fighting a lot over the past month, said that he highly doubted that Lesnar would wrestle again.

"I don't know if he is or isn't, I would find that hard to believe," said White on Lesnar returning to wrestling. "The Undertaker's been coming for a long time, he's a fan of mixed martial arts and Brock is one of his guys. Those guys wrestled together... If those guys were going back and forth, it's because they're friends."
