There have been protracted talks between the two camps of World Boxing Council champion Fury and Joshua, a former holder of the sport’s other major heavyweight titles.
Only last week the deal, based upon a 60-40 split in Fury’s favour, was said to have been accepted by Joshua’s management team.
Veteran promoter Frank Warren said a contract had been sent to Joshua’s camp.
Eddie Hearn, the promoter of Joshua, added minor issues remained to be resolved ahead of a fight expected to take place before the end of this year.
Fury, however, is now convinced Joshua is trying to back out, prompting an expletive-filled social media post about his rival on Friday.
