Amir Khan pressed his case Tuesday to overturn a controversial loss to Lamont Peterson and force a rematch while his promoter expressed concern Khan might not have a chance to avenge that defeat. Hometown hero Peterson won a split decision over Khan in Washington on Dec. 10 for the World Boxing Association and International Boxing Federation light-welterweight titles. Referee Joe Cooper took two points from Khan for shoving Peterson, the last in the final round, and two judges gave Peterson a 113-112 victory. The third saw Khan a 115-110 winner. Peterson improved to 30-1-1. Khan fell to 26-2. “The referee in a way stole that fight from me,” said Khan, who would have kept his crowns in a draw without the 12th-round deduction. “Everywhere I went people said I got robbed. All I want is a fair fight. I think I deserve it.” Khan's camp has appealed to the WBA, IBF and Washington's boxing commission. The sanctioning bodies will investigate Khan's claims of wrongdoing and are expected to hold a hearing on the matter in New York around Jan. 19.
