Former WBA heavyweight champion David Haye is set to announce his return to the ring on Thursday.
The 32-year-old beat Dereck Chisora in a fight last July sanctioned by the Luxembourg Boxing Authority.
Neither was given a licence by the British Boxing Board of control following their brawl in Munich in February last year.
Haye has consistently expressed his desire to fight WBC heavyweight champion Vitali Klitschko.
However, the WBC champion has so far resisted Haye's advances, while the Ukrainian's brother Wladimir, the IBF, WBO and WBA champion who beat Haye in 2011, will face Francesco Pianeta in May.
Haye, who won WBA, WBC and WBO titles at cruiserweight, retired in October 2011 following the defeat by Wladimir Klitschko before reversing his decision in order to meet Chisora.
Speaking in September, Haye said: "[Vitali] is the only fight that interests me at heavyweight and the WBC world heavyweight title is the one belt I'm desperate to win before I retire for good."
Russia's Alexander Povetkin is another possible opponent for Haye, while fellow Britons Tyson Fury and David Price are among the other options in the heavyweight division.
