Lindsey Tucker, the IBF championships chairman said: "We have ordered an immediate rematch between Carl Froch and George Groves.
"After a fight our rules say a boxer has 10 days to file an appeal. Groves did that, and at a hearing on January 15 in Newark we had a three-man panel review all of the evidence and they came back with the decision we must order a rematch.
"The 90 day period starts from Friday, January 24 and I'm pretty sure Carl Froch will have already received notification.
"If he fails to defend the belt against Groves within this period it's more than likely he will lose his title.
"The fighters and their teams have a certain amount of time to come to an agreement and if they can't, it will come down to purse bids."
She added: "If for some reason Froch gave up the title then we would order the two highest-rated guys to fight for the vacant belt.
"Since we already ordered Groves to fight Froch, he would be likely to be one of the guys to fight for that vacant title."
Carl Froch has been ordered to give rival George Groves a rematch within 90 days or be stripped of his world title by the International Boxing Federation.
Froch claimed on Friday that Groves rejected "a seven-figure sum" for a second chance after their controversial fight in November, which the champion won with a contentious ninth-round stoppage to keep his WBA and IBF belts.
Groves admits he has turned down an offer but is adamant he is as eager as ever to get back into the ring with Froch, and his cause has been helped after the IBF decided the bout was controversial enough to merit an immediate rematch.
