Carl Froch and George Groves have finally agreed to a rematch of last November's blockbuster, promoter Eddie Hearn has announced.
The British super-middleweight rivals will clash for a second time on 31 May to settle the dispute over Froch's controversial ninth-round stoppage at the Manchester Arena.
Froch's IBF and WBA titles will be at stake once again, and news of the rematch will be welcomed across the sport.
"Quite simply, I believe this is one of the biggest fights in British boxing history," Hearn said.
"It was one of the most epic and exhilarating fights I've ever witnessed and I'm delighted the public are going to get a chance to see it all again.
"The unanswered questions from the first fight may now be answered.
"Get ready for a whirlwind of a build-up and an event and fight for the ages – Froch v Groves II is on!"
Underdog Groves floored Froch in the first round and was ahead on the scorecards having dominated the fight when referee Howard Foster intervened as the resurgent Froch fired a barrage of shots.
Although the tide appeared to have turned against Groves, Foster's decision to step in as the 25-year-old came under pressure was widely condemned for being too early.
It was a spectacular fight but Froch has been reluctant to grant the rematch, seeking instead a Las Vegas showdown with Julio Cesar Chavez Jr.
Hearn stated at the end of last month that negotiations were proving "frustrating", even once the IBF had stepped in to order they clash again.
