An elbow injury has forced Mark Munoz out of next week’s UFC on Fox 2 co-main event bout against Chael Sonnen in Chicago.
Munoz will be replaced by Michael Bisping, who will now fight Sonnen to determine the next challenger for middleweight champion Anderson Silva.
Bisping had been scheduled to fight Demain Maia on the card. Maia will now fight Chris Weidman.
Also: The Ultimate Fighting Championship postponed its March show in Montreal.
UFC 145 was scheduled for March 24 at the Bell Centre. But the UFC scrapped it for now, citing scheduling complications and a desire to deliver a “championship card.”
UFC director of Canadian operations Tom Wright said he expects Montreal to stage a show later this year.
Most of the fights announced for the March show will be shifted to a card set for April in Atlanta.
Former Strikeforce light heavyweight champion Muhammed “King Mo” Lawal tested positive for a banned steroid following his win over Lorenz Larkin on a card at the Hard Rock Hotel on Jan. 7, the Nevada Athletic Commission announced Tuesday.
He has denied using any illegal substances. Lawal, who has the right to appeal, faces a one-year suspension, a fine and a reversal of his victory to a no-contest.
