LONDON: WBC title holder Tyson Fury and WBA, WBO and IBF champion Oleksandr Usyk will fight for the undisputed world heavyweight crown in Riyadh, it was announced on Friday. Additional details, including the date of the contest, will be released soon. “Delighted to finally get this fight signed. This is the biggest fight that could possibly be made in our sport,” Queensbury promoter Frank Warren said. “The heavyweights always spark the imagination of the fans and I have no doubt this will be the biggest boxing event of the century.” Usyk’s promoter, Alexander Krassyuk, said: “I can’t believe that it’s happening but it is.” Usyk, who has won all 21 of his professional bouts, defended his titles against British fighter Daniel Dubois in August. Fury will fight a non-title bout against MMA star Francis Ngannou on Oct. 28, also in Riyadh. That fight is part of the Riyadh Season of events for 2023. Earlier talks for a Fury-Usyk fight to be staged at Wembley Stadium in London in April fell apart. The last fight to crown an undisputed heavyweight champion was in 1999, when Lennox Lewis beat Evander Holyfield.
