Even after a failed doping test earlier this year, Andre Berto insists he has always been a clean fighter.
The former welterweight champion believes the only way to overcome the stigma on his name is by getting back in the ring with his eyes on another belt.
Berto and Robert Guerrero met Tuesday at the Grammy Museum to announce their Nov. 24 welterweight title bout in Ontario, California.
Berto realizes his reputation was indelibly stained by a positive test for norandrosterone in May, scrapping his scheduled rematch with Victor Ortiz at Staples Center.
The fighter and his camp claimed the positive test resulted from contamination. The California State Athletic Commission believed them, licensing Berto in August.
Guerrero says he has no idea whether Berto is telling the truth.
