Australian Olympian boxer Michael Katsidis (American based) retaining his title while fighting in London. Impressive as he was considered by the gamblers to be the underdog, despite being the Champion. Kevin Mitchell, the challenger, relinquished his unbeaten record in British professional boxing of 31-0.

Michael retained the WBO interim lightweight title.
