Former world heavyweight champion David Haye will announce on Tuesday he is to return to the ring after an absence of more than three years.

Haye, who has not fought since he stopped fellow Briton Dereck Chisora in 2012, is to hold a news conference at London's O2 Arena at which his next opponent will also be present.

The 35-year-old has been training with Shane McGuigan - son of former world champion Barry - and has indicated he wants to reclaim the world title he lost to Wladimir Klitschko in 2011.

Legendary former world heavyweight champion George Foreman believes Haye could be the only person who can take the belt from Ukrainian Klitschko.

Londoner Haye tweeted: "You sure know your stuff George Foreman and you'll be happy to know I'll be back to regain the heavyweight crown #HayemakerIsBack."

Klitschko, 39, is preparing to fight another Briton, Tyson Fury, in Germany on Saturday. He has not lost a fight since 2004.

Former two-weight world champion Haye - who has won 26 of his 28 bouts - says he has had offers to fight Liverpool cruiserweight Tony Bellew, Irishman Martin Rogan, American Malik Scott and Mark de Mori of Australia.
