Tyson Fury says his long-awaited heavyweight fight with Anthony Joshua "doesn't look like it's going to happen" in a rant at his British rival and promoter Eddie Hearn on Friday.
Joshua and Fury are expected to meet in the 'Battle of Britain' on November 20 with Madison Square Garden in New York emerging as a likely location.
But Fury accused Hearn of 'wanting more money' from Saudi boxing supremo Turki Alalshikh and funding other ventures off the back of the prospective Fury-Joshua fight.
In a post on Instagram, Fury, 38, said: "Doesn't look like they're going to sign the fight, doesn't look like it's going to happen. All because Eddie Hearn and that want more money.
"They have already had that much money off Turki (Alalshikh) over the last few years Eddie and AJ. They have had boxing deals, they have had darts deals, they have had snooker deals, they have had everything.
"And yet, they have got the audacity and cheek of flea-bitten rats to ask for more money from old Turki that you have had combined over the last couple of years."
Hearn had revealed it was written into 36-year-old Joshua's contract that the fight had to be staged in Britain. However reports of an agreement to fight at New York emerged this week.
Fury is threatening to fight a different opponent in November if an agreement with Joshua is not reached.
