If you are looking forward to seeing Chael Sonnen and Wanderlei Silva finally lock horns on May 31, don't get your hopes up too high.

The two rivals are set to do battle following series 3 of The Ultimate Fighter Brazil which is currently underway, but according to "The American Gangster", Silva has been acting very strange and he doesn't think "The Axe Murderer" will show up on May 31:

"It's one of those things where, something stinks here." Sonnen told MMAFighting.com "He's talking more than ever. He's saying things like ‘Chael better not get hurt' and ‘Chael better not fall out.' I've never pulled out, ever. If I'm hurt or I'm sick, I just show up.

Never do I complain or I pull out. What that's telling me, he's going to claim he's hurt. He's just doing all these things to tip his hand here, and something stinks and I don't know what it is, but something's going on."

Silva has been out of action now for over a year dealing with multiple injuries. The Pride legend hasn't fought for over a year now since UFC on Fuel TV 8 where he knocked out Brian Stann in one of the most thrilling fights of the year.

The Brazilian appears to be back to full health and ready to fight, but Sonnen says that's not the case. The former UFC middleweight title challenger said Silva never trained at all during the filming of the series while he was working away hard:

"I was with him on the set of The Ultimate Fighter, and I watched him every day not practice. It seemed like he watched me every day twice a day practice. I'd see him in the hallway and he'd see me covered in five or six pounds of sweat and he'd be walking in with fruit, he was always eating pears.

He'd be walking around with a pear in his hand as dry as can be and I thought 'you don't look like a guy who's getting ready to fight,' not a five round fight, particularly not when you've been out of the ring for a year. This just doesn't make sense. He said, I need eight weeks, that's all I need to get my body ready, and in eight weeks I'm going to get ready."

Sonnen does seem to be serious here, but with everything he says you're best taking it with a pinch of salt. For now the two rivals are scheduled to settle their differences next month at TUF: Brazil 3 Finale.

What do you make of Sonnen's latest shenanigans?
