The governing body last week confirmed they wanted Peterson to defend their light-welterweight title against Khan after he beat the Englishman in controversial circumstances in his native Washington in December.
But Peterson, who will keep the IBF title regardless after Khan withdrew his appeal to that governing body, is ready to fight that judgement.
A statement from Team Peterson said: “Although rumours have surfaced we are now in negotiations for a Peterson vs Kahn rematch in Washington DC, at this time there are no open negotiations for this bout. The Peterson team’s focus is on the WBA’s decision mandating an immediate rematch. A comprehensive written appeal has been submitted to the WBA and we are confident the WBA will overturn its decision mandating an immediate rematch and recognise Lamont Peterson as the true and final WBA Jr(light) Welterweight World Champion.”
Peterson’s team contend Khan withdrew his appeal to the IBF because his case was not sound, although Khan’s team understandably claim the absence of referee Joe Cooper and WBA supervisor Michael Welsh were the key reasons behind their lack of faith in the hearing.
Peterson’s trainer, manager and mentor Barry Hunter said: “We are extremely pleased Golden Boy and Amir Khan withdrew their protest with the IBF.
“As we have said all along, we were not going to be forced to make a decision by one person or entity and we will continue to do what is in the best interest of Lamont Peterson.
“The Peterson team continuously responded to each of Khan’s accusations and the absurdity of the claims. Our reply addressed the rules and also Khan’s inability to make adjustments and his performance in the ring, as opposed to placing blame on almost everyone associated with the bout.
“We have an open mind and look forward to Lamont’s first title defence. We will discuss internally and asses every viable opportunity available. We will then make the best decision possible for the future of Lamont and his family.”
Peterson himself said: “Now that this is over I am ready to move on.”
