UFC heavyweight champion Brock Lesnar supposedly flipped out during the UFC 100 Countdown show, according to a recap by Dave Meltzer posted on wrestling-edge.com.

Here is Meltzer’s recap of the show:

“Frank Mir does an awesome job of building up Lesnar vs. Mir. So awesome that by the end he almost turned himself heel. There is a great scene when Lesnar decides the interview is over because he’s sick of watching himself tap and wants to kill Steve Mazzagatti, walks down the hall, punches the wall, and the next door falls off the hinges into the hallway.”

UFC 100 Countdown: Lesnar vs. Mir will be premiering July 7 at 10 p.m. ET/PT on Spike TV.
