James DeGale and Chris Eubank Jr will have the controversial IBO world super middleweight title on the line in their grudge match at the O2 Arena on February 23.
The much-maligned belt is considered by many fans to be less credible than those offered by the four main organisations – WBO, WBA, WBC and IBF.
Eubank Jr won the belt in February 2017 with a win over Renold Quinlan and it has remained vacant since his loss to George Groves, who subsequently gave up the belt rather than paying the sanctioning fees.
He will now attempt to recapture the crown and he takes on former IBF champion DeGale , who vacated the much more prestigious strap to make the all-British battle.
Head of the IBO governing body Ed Levine confirmed the news, saying: “I am very excited for the upcoming IBO World title contest between James DeGale and Chris Eubank Jr.
"I believe this is the most intriguing matchup in the Super Middleweight division at the moment, and I will be delighted to see either one of the fighters emerge as IBO World Champion as they will have earned it the hard way.
“Fights like DeGale and Eubank Jr are the fights that fans want to see, and we want to have contested for IBO titles."
Meanwhile, the bout has been picked up by Showtime for live coverage in the United States.
The fight takes place in ITV Box Office in the UK, but the American broadcasters have picked up the rights to show the card across the pond.
