Tyson Fury has confirmed he will fight British heavyweight rival David Haye in Manchester on 28 September.
Former WBA heavyweight champion Haye, 32, has not fought since a fifth-round stoppage victory against Dereck Chisora in July 2012.
Fury, 25, was last in action in April when he spectacularly stopped American Steve Cunningham in the seventh round of their bout in New York.
The Haye v Fury contest will take place at the Manchester Arena.
A joint statement from both camps said: "David Haye and Tyson Fury, both world-ranked, charismatic and dangerous, have agreed to a highly-anticipated domestic showdown on Saturday, 28 September at the Manchester Arena.
"It marks not only the biggest heavyweight encounter of 2013, but also the biggest fight staged in Britain for many years."
Haye, who has also held the WBA, WBO and WBC cruiserweight titles, withdrew from a June date with Manuel Charr because of a hand injury sustained in training.
A defeat by Wladimir Klitschko in October 2011 led to Haye announcing his retirement, but he reversed his decision in order to meet Chisora in 2012.
Prior to the confirmation of his meeting with Fury, Haye had goaded the Manchester-born fighter on Twitter, saying: "Lets hope he finally agrees and doesn't keep delaying.
"Word is he's looking to duck me and fight Tony 'The Tiger' Thompson. Lets hope they're just rumours."
Haye and Fury will officially confirm details of the fight at a news conference scheduled for London on Thursday.
