Dana White announced today via Twitter that Mark Munoz will not face Chael Sonnen on the UFC on Fox fight card. An injury has forced the top Middleweight off of the card and he will now be replaced by Michael Bisping who was originally scheduled to face Demian Maia.

"Munoz is injured and out of the FOX fight," White posted via Twitter. "Now it's Chael Sonnen vs. Mike Bisping Jan. 28, and the winner will fight Anderson for the title."

It is still unclear the severity of Munoz's injury. Demian Maia will now face Chris Weidman. The winner of the Sonnen vs Bisping fight will then move on to face long time Champ, Anderson Silva for a title fight in the near future.
