The very same day that Chael Sonnen released a video update about his rivalry-fueled coaching stint opposite Wanderlei Silva on The Ultimate Fighter Brazil 3, a report has surfaced that the two teams have come to blows on the set of the show.

UFC President Dana White spoke up at a Monday media luncheon to say that a fight erupted where one of Silva’s team sucker punched Sonnen in the fracas (transcribed by MMAFighting.com):

"Wanderlei and Chael fought," White said. "Just today. They literally fought. While they were fighting one of Wanderlei's guys sucker punched Chael. They went crazy, crazy s--- happened there. We're dealing with that right now too. ... They literally fought today, it went on for awhile."

While there was no exact report to clarify the details of the situation, it’s clear that the heated exchanges between bitter enemies Sonnen and Silva reached a fever pitch in no time at all. While that may not come as a surprise, it wasn’t something that was necessarily needed to promote their upcoming fight according to White:

"It's one of those things, it's on a reality show, it's good and it's bad," White said. "A fight didn't need to break out between these two for people to be excited about this fight, because these two have been at each other's throats."

Indeed they have had a mutual hatred of one another for quite some time now. The day has arrived where Sonnen and Silva should put their rivalry to rest once and for all. But with filming barely underway in Sao Paulo, will they make it through the preceding season of TUF?
