Carl Froch ordered to have George Groves rematch by IBF

World super-middleweight champion Carl Froch has been ordered to have a rematch with George Groves within 90 days or risk losing his belt.

The International Boxing Federation has told the pair to fight again following an appeal by Groves after Froch's controversial stoppage in November.

Earlier today, Groves, 25, turned down an "unsatisfactory" rematch offer. ‏

After the IBF's decision, he tweeted:  "Maybe I was right after all turning down that 'amazing' offer."

Nottingham fighter, Froch, beat Groves in Manchester on 23 November with a stoppage in the ninth round, but the decision was met with a negative response from sections of the crowd.

Afterwards, Groves insisted the contest had been ended too soon.

"Groves thought the fight was stopped early. The panel, three members, listened to all the evidence and they decided a rematch was in order," IBF Championships chairman Lindsey E Tucker told BBC Sport. "I guess… they ordered the rematch after his complaint."

Tucker said Froch had 90 days to fight again and that if he failed to do so, he would "probably" lose his IBF title.

He added: "Both fighters were notified of the decision right away. We've heard responses from both parties but I'd rather not say what they said. They both acknowledge the decision."

Froch, 36, said on Friday morning he would aim to arrange a fight with Mexico's Julio Cesar Chavez Jnr after revealing Groves had rejected a "seven figure" offer for a rematch.

But Groves then insisted negotiations were ongoing and that he was waiting for the outcome of the IBF's decision on his appeal.

Following the IBF's ordering of a rematch, Groves said on Twitter: "Now everyone understands Carl Froch press release today. Wants to move on? Hold on honey, IBF says NoNoNo. Rematch or vacate."
