UFC president Dana White today announced via Twitter an injury has forced Munoz to withdraw from a planned UFC on FOX 2 meeting with Chael Sonnen (26-11-1 MMA, 5-4 UFC), who now meets British slugger Michael Bisping (22-3 MMA, 12-3 UFC) instead.
The two clash on the FOX-televised main card of this month's "UFC on FOX 2: Evans vs. Davis" event, which takes place Jan. 28 at Chicago's United Center.
"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."
