Anthony Joshua and Tyson Fury's world heavyweight title showdown has moved a step closer with Joshua's promoter Eddie Hearn saying a two-fight deal has been signed.
The winner of the all-British bout will become the undisputed heavyweight champion.
The locations and dates are yet to be confirmed.
Joshua holds the WBA, WBO and IBF belts, while Fury has the WBC title.
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 recognized as undisputed champion.
Joshua has a record of 24 wins and one defeat from 25 professional bouts.
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.
