Chael Sonnen says 'fat, stressed' Wanderlei Silva wants out of UFC 173 fight

Chael Sonnen and Wanderlei Silva are set to cap their tenure coaching The Ultimate Fighter:Brazil with a co-main event at UFC 173. Sonnen thinks Silva wants out. Here's what he emailed to Fighters Only:

"Wand is fat. He hasn't taken his shirt off since we have been here," Sonnen writes by email.

"He thought our fight would be in July, but it got announced for May. He's stressed and trying to get out of it."

Sonnen and Silva got into a brawl on the TUF set last week and were eventually separated but not before Silva's coach Andre Dida caught Sonnen with a couple of punches to the back of the head.

UFC president Dana White commented about the scuffle at the UFC 169 scrum via MMA Mania:

"I wasn't shocked. That thing has been a time bomb since they got there. It's without a doubt the worst thing that's ever happened on The Ultimate Fighter in 20 seasons."

When asked if he would use the incident as a promotional tool -- TUF: "Brazil 3" will soon stream online via "Fight Pass" digital network -- White said the rivalry between the two speaks for itself and that no promotion is needed to sell it.

"That fight we can do no commercials, no newspaper, no radio, no nothing and that would, people want to see that fight. No, I don't like guys fighting outside of the Octagon. It's never happened. If you look at all the guys that we've had in there and who have gotten in each others faces and who have done what they've done, it's never come to a real fight. And I told them, 'hey, you idiots want to fight for free? Okay, I'd love to not pay you. It's going to be a big fight, I'll not pay you.' It's crazy. That's how bad they dislike each other."

Stay tuned for developments.
