Kiev - The Ukrainian heavyweight boxer Wladimir Klitschko on Wednesday accused US boxing promoter Don King of blocking an undisputed world heavyweight title bout against Russian Nikolai Valuev.
Klitschko, 33, holds the IBF, WBO, and IBO world heavyweight titles. A fight between Klitschko and Valuev, holder of the WBA heavyweight belt, would arguably make the winner the world's unchallenged top heavyweight fighter.
Wladimir Klitschko's older brother Vitali, holds the WBC belt, but both Klitschkos have rejected the idea of their ever fighting each other.
