Even with the recent press conference and the signed contracts, WBO/IBO/IBF heavyweight champion Wladimir Klitschko (55-3, 49 KOs) is still worried that his upcoming unification with David Haye (25-1, 23 KOs), the WBA champion, is going to get canceled. Back in 2009, Haye also signed a contract to face Wladimir and later withdew with an injury. Haye later agreed to face older brother Vitali Klitschko and once again withdrew in order to take a fight with then WBA champion Nikolai Valuev.

“I will not believe this fight until I see David Haye in the corner July 2,” Klitschko said  to the New York Post. “Thank God, he is going first. Then I’ll see, OK, he’s there, then I’ll come in.’“
