Former UFC heavyweight champ Brock Lesnar was beat on for a full round by Shane Carwin without being finished. He’s also taken shots from Heath Herring, Frank Mir, and Randy Couture. Now with Alistair Overeem coming up at UFC 141 on Dec. 30th people are starting to question Lesnar’s chin and frankly it pisses him off.

Lesnar talked with MMAFighting.com about the matchup earlier this week and stands by his claim that he has never been knocked out.

“I think it’s a bunch of bulls—,” Lesnar said. “The fights that I’ve gotten hit, I’ve stood and banged with Heath Herring, Randy Couture, Frank Mir — I’ve taken a lot of shots. I mean, Shane Carwin. And I’ve yet to be knocked out. I had refs stop a fight for a submission and a TKO, which is a referee stoppage. I’ve never been knocked out cold.”

Lesnar wasn’t knocked out by Cain Velasquez last Fall but the ref stopped the fight because Brock wasn’t defending himself. If it had continued the former WWE champ probably wouldn’t be able to make these claims about his chin.
