UFC On Fox 2: Mark Munoz Out, Michael Bisping In Against Chael Sonnen

Less than two weeks out from the UFC's sophomore effort on Fox, the injury train has derailed once again.

Middleweight co-headliner Mark Munoz has been scratched from the UFC on Fox 2 fight card due to an undisclosed arm injury. Polarizing contender Michael Bisping will now duel Chael Sonnen on the Fox broadcast, with the winner receiving the next shot at UFC middleweight champion Anderson Silva.

No word has been issued regarding the fate of Bisping's prior opponent, Demian Maia.

UFC President Dana White announced the news via Twitter on Tuesday afternoon.

Sonnen (26-11-1) cruises into the bout after a hard push for a rematch with Silva failed to come to fruition due to several injury complications. The self-proclaimed "people's champion" last fought at UFC 136, where he thoroughly dominated rising contender Brian Stann en route to a second-round arm triangle choke.

"I am going to knock the teeth out of this snot nosed Brit who calls himself royalty, who calls himself a Count," Sonnen wasted no time in declaring. "I am MMA royalty and America will tune into the Chael Sonnen show next Saturday on Fox."

Bisping (22-3), meanwhile, leaps into the spotlight after punctuating his stint on "The Ultimate Fighter 14" by crushing Jason "Mayhem" Miller in December. The one-sided victory pushed the 32-year-old's win streak to four straight. Four years into his middleweight run, Bisping has now racked up notable wins over Jorge Rivera, Yoshihiro Akiyama, Dan Miller, Denis Kang and Chris Leben.

"Chael Sonnen's best weapon is his mouth, and that's something that's going to be absolutely useless in this fight," Bisping shot back. "I see a very bright future for Chael Sonnen as a used car salesman, very soon.

"He's been kicked out of politics, kicked out of real estate, and I am going to kick him out of the middleweight division."

UFC on Fox 2 is slated for January 28, 2012 at the United Center in Chicago, Illinois. A light heavyweight battle between Rashad Evans and Phil Davis headlines the network broadcast.
