Former world middleweight boxing champion Felix Sturm of Germany has lost to another Australian after Sam Soliman claimed a unanimous points victory in their IBF middleweight title eliminator. Sturm, 34, suffered a second consecutive defeat in Duesseldorf on Friday night having lost his WBA crown to Australia's Daniel Geale last September. The former champion suffered the fourth loss of his career after a plucky display by Soliman, to whom the judges awarded the fight 116-111, 114-113, 114-113, to give the 39-year-old Australian a record of 43 wins, 17 KOs and 11 defeats.
