It has now been confirmed that Tyson Fury and Oleksandr Usyk will fight for the undisputed heavyweight title on 17 February in Saudi Arabia.
Fury, a Briton is the WBC champion with Ukraine’s Usyk, 36, holding the WBA, WBO and IBF belts.
The winner in Riyadh will become the first undisputed heavyweight champion since 1999.
The bout was scheduled to take place on 23 December but Fury’s difficult encounter with Francis Ngannou last month derailed those plans.
Instead on that date, in Riyadh, former heavyweight world champions Anthony Joshua and Deontay Wilder will fight separate opponents.
Should Joshua overcome Otto Wallin and American Wilder beats former champion Joseph Parker, the pair could fight each other in 2024.
Fury has won 34 fights with one draw since turning professional in 2008.
He has faced criticism for failing to reach terms with Usyk after a proposed bout at London’s Wembley Stadium in April fell through.
Fury had been expected to cruise past former MMA champion Ngannou – making his boxing debut – in a non-title fight, but narrowly edged a split-decision success.
The last undisputed heavyweight champion was Briton Lennox Lewis, who beat Evander Holyfield in Las Vegas to defend the WBA, WBC and IBF titles.
No heavyweight has held all four of the recognised world titles.
Never has there been a four-belt heavyweight undisputed world champion.
Fury and Usyk have sat firmly at the top of the division ever since the Ukrainian dethroned Joshua. The winner will now cement their legacy as the greatest of their generation.
The two came face-to-face at an intriguing news conference in London on Thursday.
