UFC light heavyweights Chael Sonnen and Wanderlei Silva have had a longstanding feud that has yet to generate an actual fight inside the Octagon. Today at the Olympia Expo at the Las Vegas Convention Center, Wanderlei approached Sonnen and started a confrontation that became another war of words. In the above video (which is admittedly in poor quality) you can quite clearly hear Wanderlei telling Sonnen he can "suck his d**k" before the two were separated.
Silva doesn't have a fight lined up, while Sonnen is the UFC 167 co-main event against Rashad Evans. Supposedly Silva was supposed to fight Sonnen on the November PPV, but according to Dana White he did not want to fight him unless he received PPV points.
Ultimately, nothing serious came out of this scene, but it does add another chapter to this heated rivalry.
