The IBF have confirmed they will investigate Amir Khan's defeat by Lamont Peterson after receiving a request for a formal appeal from Golden Boy Promotions.
One of the areas of the appeal will be "miscalculation of scoring" after Golden Boy chief executive Richard Schaefer on Tuesday night claimed there were irregularities in the way the scorecards were compiled and collected.
Khan was relieved of his WBA and IBF world titles by Peterson, the home-town fighter, in a decision that continues to be bitterly disputed by the 25-year-old.
The performance of referee Joe Cooper, who deducted two points from Khan for pushing, has also aroused the suspicions of Golden Boy.
An IBF statement read: "On the evening of December 19, the IBF/USBA received a request for a formal appeal procedure from Golden Boy Promotions for the bout between Amir Khan and Lamont Peterson.
"The grounds for such an appeal include miscalculation of the scoring, inappropriate conduct by officials which may affect the outcome of the bout and any alleged violation of the rules of the IBF/USBA that may have a detrimental effect on the rights of the complainant.
"The complaint by Golden Boy Promotions has been accepted by the IBF/USBA and a panel of three boxing officials will be assembled to hear the appeal and review the bout.
"After completion, the panel will present its findings to the President, who after consulting with the Championships Committee, shall take that action deemed appropriate based upon the panel's findings."
The appeal is expected to be heard in New York on January 18 and 19.
Schaefer has alleged that the IBF's master scorecard disappeared immediately after the fight, only for a different version to be produced two days later. Schaefer claims the different version was clearly made subsequently.
