Heavyweight champion Browne unsure if he can clear his name (The Associated Press)

WBA heavyweight boxing champion Lucas Browne says he’s ”completely” innocent of doping, but has no idea whether he will be able to clear his name. Browne tested positive to banned steroid clenbuterol, which boosts metabolism and burns fat, when he won his world title by beating Ruslan Chagaev in the 10th round of their fight in Grozny, Russia, on March 5. The victory made him Australia’s first heavyweight world boxing champion.
