David Haye and Dereck Chisora will go head to head at Upton Park on July 14 in a fight sanctioned by the Luxembourg Boxing Federation, according to reports.
The British heavyweight fighters hit the headlines for their conduct at a press conference after Chisora's WBC heavyweight title challenge against Vitali Klitschko in Munich on February 18.
Chisora slapped his opponent at the weigh-in and spat water at the Ukrainian's brother Wladimir just prior to the contest, before becoming embroiled in a brawl with Haye at the post-fight press conference.
Haye, meanwhile, relinquished his licence when he officially retired last October, three months after losing his WBA title to Wladimir Klitschko in Hamburg.
However, the grudge match looks set to go ahead after seemingly having been given the green light by the Luxembourg authorities.
