Wonder why Mark Munoz had to pull out of Chael Sonnen fight? Check out the junk doctors removed from his elbow

Mark Munoz lost out on a huge opportunity when he had to bail on his UFC on Fox 2 fight against Chael Sonnen.

It looks like the middleweight contender had no choice. The injured elbow that got operated on, had that stuff floating around in it.

Munoz faces 4-6 weeks of recovery time and hopes to return to the Octagon in May. Michael Bisping was bumped up the card to face Sonnen with Chris Weidman sliding into Bisping's spot against Demian Maia.
