FanHouse has learned that Carwin's bout against Cain Velasquez at UFC 104 has officially been scrapped, and the 11-0 heavyweight will main event the November 21st card in Las Vegas against Lesnar (4-1).
MMAMadness.com first reported the news of the potential title fight late Tuesday evening.
The Carwin vs. Velasquez bout at UFC 104 was supposed to determine the No.1 contender for the UFC heavyweight title. No word just yet on who Velasquez will be facing instead, but FanHouse has learned that the 6-0 American Kickboxing Academy will still be competing on the October 24 card in Los Angeles.
No official reason was given for the switch.
Carwin is 3-0 inside the Octagon, however, only one of his victories -- a first-round TKO win over Gabriel Gonzaga at UFC 96 -- has come on the main card.
Lesnar captured the UFC heavyweight crown when he defeated Randy Couture at UFC 91. He successfully defended it at UFC 100 in July, defeating interim champion Frank Mir via second-round TKO.
Carwin doesn't appear to be a big fan of Lesnar's, as he very vocal about how unimpressed he was with Lesnar's post-UFC 100 behavior:
Tito Ortiz vs. Mark Coleman is also rumored for UFC 106."The flipping off of the fans that just lined your pocket with millions of dollars is just LAME. He may be a Champion but he has a long ways to go before he earns the respect of a Champion. The fans are why we do this Brock, this sport is not about fat paychecks and drama it is about hard work and sacrifice for a shot to do what you did last night. It doesn't matter how much money you make if you can't earn your peers respect and the respect and love of the greatest sporting fans in the world. We have no scripts in this sport, no pre-determined earning amount and no pre-determined outcomes. It doesn't matter if you win or loose it matters how you win or loose."
