WBO/IBO/IBF heavyweight champion Wladimir Klitschko told Reuters that WBA champ David Haye refused to face older brother Vitali Klitschko, the WBC champion, because of his punching power.

"David Haye said he doesn't want to fight Vitali because Vitali is hitting too hard. He said he wants to take the little brother," Klitschko said. "It's the truth. The fight is going to happen. We found a date, July 2.

Klitschko will first defend his titles against undefeated Dereck Chisora on April 30. The fight was originally scheduled to happen on December 11 and canceled after Klitschko pulled out with an abdominal injury.

"I want to stay active because I fought in September, so I'm definitely going to fight on April 30 against Dereck Chisora, another British guy that I was supposed to fight in December," Klitschko said.
