The much-anticipated bout between Anthony Joshua and Tyson Fury is for the undisputed heavyweight crown is all but done after Joshua’s promoter Eddie Hearn said a two-fight deal has been signed.

The locations and dates for the all-British clash are yet to be confirmed.

Joshua, 31, holds the WBA, WBO and IBF belts, while Fury, 32, has the WBC title.

“All parties have now put pen to paper and we will be working hard over the next few weeks to confirm the site and date for the biggest fight in boxing,” Hearn told Sky Sports on Monday.

Speaking to ESPN, Hearn said they are aiming to get a venue “confirmed in the next month” and that they have already had offers from “eight or nine sites” across “multiple countries in the Middle East, Asia, eastern Europe and America”.

The fight between Joshua and Fury will see all four belts contested in a heavyweight bout for the first time.

The last undisputed heavyweight champion was Britain’s Lennox Lewis from 1999 to 2000, before a boxer had to also hold the WBO belt to be recognised as undisputed champion.

Joshua has a record of 24 wins and one defeat from 25 professional bouts. He lost his three world titles in a shock defeat by Andy Ruiz Jr in June 2019 before regaining them in a rematch in December that year.

He defended them by knocking out mandatory challenger Kubrat Pulev at Wembley Arena in December.

Fury is unbeaten in his 31 professional fights, having survived two knockdowns to draw with American Deontay Wilder in 2018 before taking the WBC title by winning their rematch in February 2020, the last time Fury fought.

He won the WBA, IBF and WBO belts by beating Wladimir Klitschko in 2015 before nearly three years out of the sport during which he overcame depression and also accepted a backdated two-year UK Anti-Doping ban.
