Dana White: Wanderlei Silva has not signed his contract to fight Chael Sonnen on May 31 in Brazil

Could all this drama have been for nothing?

Ultimate Fighting Championship (UFC) President Dana White revealed during this week's media scrum (via Bloody Elbow) that the much-anticipated light heavyweight fight between Chael Sonnen and Wanderlei Silva is far from a done deal.

"Yeah, there's a lot more to that story than I can say," said White.

While some might think the delay is coming from Sonnen's side due to the recent testosterone replacement therapy (TRT) ban in Brazil (details) and his comments about a potential retirement, White says the holdup is actually coming from the Silva camp.

Though he wouldn't reveal what the sticking point was.

"He's not balking," said White. "Not even a little bit. It's not over money, either. I can't tell you. It has to do with the show, that's all I can tell you."

Sonnen and Silva served as coaches on The Ultimate Fighter (TUF): "Brazil 3" (check out our episode one thread here) but if "The Axe Murderer" doesn't sign on the dotted line, and soon, this fight may just go up in smoke.

It would be a shame, too, seeing as how the build up to their fight -- which is scheduled to take place on May 31, 2014 in Brazil -- has been rather intense. And, should this bout not come to fruition, the hatred between these two men will continue to linger.

Maybe UFC matchmakers can convince Cung Le to flip the script and step in to face "The American Gangster."
