By James Slater: I didn’t think it would take long for former 140-pound champ Amir Khan to give his opinion on the recent decision by the IBF to allow Lamont Peterson to retain his position as their 140-pound world champion. Khan, who was controversially out-pointed by Peterson last December, by a Peterson who was later caught taking PED’s, was never going to be happy that the IBF failed to follow the lead of the WBA and strip the admitted cheat.
