BoxingScene.com was advised by promoter Frank Warren that WBO/IBO/IBF heavyweight champion Wladimir Klitschko has suffered a back injury and withdrew from Saturday's fight with unbeaten British champion Dereck Chisora.
"I was informed about an hour ago that Klitschko pulled a back muscle and he was out of the fight. Dereck is very disappointed. He didn't believe it. He felt everything was fine. Three or four days before a title fight, most of the hard work is done," Warren told BoxingScene.com.
There are talks to reschedule the fight. Klitschko's team have to speak with Germany network RTL to get a new date.
