Just when it appeared as though MMA had an official date/location for the immensely anticipated rematch between UFC middleweight champ Anderson Silva and controversial grappler Chael Sonnen, it now looks like there may be a hitch. Though the UFC announced the bout would take place on June 23 at UFC 147 in Rio de Janeiro, Sonnen hasn’t actually inked any sort of paperwork.

While doing so could be a formality, the 185-pound contender isn’t so sure it will be that simple.

“My demand has not been met,” said Sonnen to MMAFighting, adding he’d signed nothing and would let the world know his terms in the immediate future.

The two talented middleweights first met in 2010 after a build full of trash-talk, the bulk of which primarily came from the 27-11-1 Sonnen. In the bout Sonnen nearly came away with a dominant decision win but slipped up with less than two minutes remaining and got caught in a Triangle-Armbar, giving Silva a submission win. Both are unbeaten since with Sonnen taking out Michael Bisping and Brian Stann while Silva has stopped Vitor Belfort and Yushin Okami respectively.


MMATraining Take: If Sonnen makes any sort of ridiculous demand he’ll have painted a yellow streak down his back to match the one he claims Silva has. With the venue is set and the company on board there’s no reason this fight shouldn’t happen.
