"Golden Boy Promotions, on behalf of former unified junior welterweight titleholder Amir Khan, is moving swiftly in an effort to have the result of Khan's split-decision title loss to Lamont Peterson in December overturned to a no-contest and the belts returned to Khan in the wake of Peterson's failed drug test.

Golden Boy attorney Arnold Joseph wrote letters on Friday to Alfred Grant, deputy commissioner of the Washington, D.C., Boxing and Wrestling Commission, asking the fight result be changed to a no-contest.

Joseph also wrote to Daryl Peoples of the IBF and Gilberto Mendoza Jr. of the WBA, the organizations that sanctioned the world title bout on Dec. 10, asking for the titles to be returned to Khan."
