Chris Meyer, General Manager of Sauerland Event, says unified world heavyweight champion Wladimir Klitschko (59-3, 50KOs) has until August 31st to make his mandatory defense against WBA "regular" champion Alexander Povetkin (25-0, 17KOs) of Russia. Meyer says K2 Promotions tried to get the financial split changed from 85-15% in Wladimir's favor, but the WBA kept the split of the orginal order, 75-25. Wladimir will first make a voluntary defense against undefeated Francesco Pianeta on May 4th in Hamburg, Germany.
