Wladimir Klitschko (born 25 March 1976) turned professional with Universum Box-Promotion in Hamburg under the tutelage of Fritz Sdunek, often being featured on fight cards alongside his elder brother Vitali. After building an undefeated record of 24–0 with 21 KOs, he suffered his first loss to Ross Puritty, in what was Klitschko's first and only professional fight in Ukraine. Puritty forced Klitschko, who had at that time not gone beyond 8 rounds, to punch himself out. Klitschko began to be overwhelmed in the 10th round and went down twice but was allowed to continue. At the start of the 11th round, with Puritty continuing to land hard punches, Klitschko's trainer, Fritz Sdunek, entered the ring and stopped the fight.

Ross Puritty (born December 18, 1966 in Norman, Oklahoma) is a retired heavyweight professional boxer. A high-level journeyman and occasional heavyweight contender, Puritty is best remembered for his shocking upset of Wladimir Klitschko in 1998 that won him the WBC international Heavyweight title.
