London - The WBA has handed Amir Khan an "immediate rematch" with Lamont Peterson following the Briton's controversial loss to the American.
Khan lost a split decision - as well as his WBA and IBF light-welterweight titles - to Peterson in Washington in December.
However, the fight was dogged in controversy with Khan docked two points for pushing by referee Joe Cooper, while a "mystery man" - later identified to be Mustafa Ameen - was seen at ringside appearing to handle the scorecards.
Khan also claims he was told he had won the fight only for the Peterson to be awarded the decision after a long wait for the result.
Khan's promotional team Golden Boy had appealed the decision to both the WBA and IBF - wanting the bout to be declared a "no-contest" and for a rematch to be ordered.
The WBA have made the first move by agreeing to a rematch, with the IBF - to whom Ameen is affiliated - will make a decision next week.
Golden Boy Promotions' Richard Schaefer, who represents Khan, told ESPN.com: "The WBA ordered an immediate rematch. I'm thrilled that he's getting one and hope we can start the negotiations and get the fight done.
"Amir and Lamont are both terrific young men and athletes who fought their hearts out in Washington in December and I'm sure this decision will get applause by fight fans around the world.
"The rematch will be one of the most anticipate fights of 2012 because both guys are exciting, young and I think it's exactly the kind of fight people want to see."
