LONDON (AP) -- Lamont Peterson says he's ready to defends his WBA and IBF light-welterweight titles against British challenger Amir Khan in a rematch of their disputed fight last year.
Khan lost both belts in a split-decision loss to the American on Dec. 10. But he complained about the referee's decision to deduct two points for pushing and the presence of an unauthorized man at ringside seen distracting an official.
They will fight May 19 in Las Vegas.
Peterson says Khan's complaints took the shine off his victory and his opponent "has to accept he's not the champ anymore."
