Frank Warren has suggested Tyson Fury and Anthony Joshua's heavyweight showdown could be postponed if there is no agreement on a venue.
Queensberry promoter Warren remains confident that the eagerly-anticipated 'Battle of Britain' will go ahead as planned in November, despite question marks over where the fight will be staged.
Wembley was the initial frontrunner until an issue over the start time emerged, and Madison Square Garden in New York is now the favourite with Saudi boxing chief Turki Alalshikh believing the U.S. serves a wider global audience better.
Joshua's promoter Eddie Hearn said this week they would not have signed the contract if the fight was in America and there has to be a "discussion around that."
Responding to Hearn's comments, Warren told Box Nation: "Tyson Fury has his agreement, which states something different. The fight will happen.
"I've heard what Eddie has said. They're either going to agree to it or not. If they don't agree to it then the fight won't happen.

"Tyson signed for the fight back in January; the fight was supposed to happen in September.
"They were supposed to have a warm-up fight in September; unfortunately there was that terrible, tragic accident that AJ was in where he lost two of his best friends, and that held everything up.
"But the fight I understand, will be November, and the venue will be announced in due course."
