Los Angeles, CA -- (Sports Network) - Former light middleweight champion Ronald "Winky" Wright injured his left hand while sparring and was forced to cancel his scheduled December 4 bout against Michi Munoz.

Wright (51-4-1, 25 KOs) hasn't fought since July 2007 when he lost a unanimous decision against Bernard Hopkins in Las Vegas.

"I'm very disappointed about having to pull out of this fight on December 4, and I'd like to apologize to all my fans," said Wright. "I was feeling real sharp in camp and I was looking forward to a great performance before getting hurt. I promise that I'll be back and better than ever in 2009."

The entire Wright-Munoz card, which was scheduled to take place at the Snoqualmie Casino in Snoqualmie, Washington and be televised by Versus, has been canceled and will not be rescheduled.
