Middleweight contender Mark Munoz has withdrawn from a No. 1 contender fight against Chael Sonnen at UFC on Fox 2 on Jan. 28 due to an injured right elbow.
Munoz (12-2) was flown to UFC headquarters in Las Vegas last week to meet with physicians. The injury will require the 33-year-old fighter to have surgery. His recovery time is currently unknown.LINK
