Tyson Fury's promoter Frank Warren is confident the long anticipated fight with Anthony Joshua will happen and said Fury's training has already begun in Miami.
The status of the fight has been a source of contention over the past week after Fury's comments that it "doesn't look like it is going to happen," referring to debate over the potential venue.
While a date in November seems to have been agreed, where the fight takes place is a sticking point as Fury and Joshua have signed separate contracts with Saudi Arabian-owned organisers Sela.
However, Warren has stated he believes the fight will go ahead and revealed Fury has already landed in Miami to begin training.
"I definitely think [the fight] will happen," Warren, who is is promoting Moses Itauma-Filip Hrgovic on Saturday, told Sky Sports.
"I think [Turki Alalshikh] will announce it fairly soon. I know there's been some issues with contracts with Matchroom and 'AJ'.
"I believe they'll iron those out.
"In the meantime, Tyson has flown off to the States, he's in Miami and he's preparing for the fight."
Warren went on to say that if the bout were to be hosted in the United States, it wouldn't be a surprise.

"I think they both want the fight at Wembley, but it's out of their hands now. Well, that's not quite right, they could refuse to fight. But then we don't get the fight that everyone wants to see," he said.
"I think because the amount of money that they're getting paid, I believe it will go on.
"I hope I'm wrong, but I think it will go on in America, for obvious reasons ... But that's nothing unusual; you had massive, massive American heroes, in Muhammad Ali and George Foreman, Vegas wanted it, Madison Square Garden wanted it, and it went off to Zaire in 1974.
"People thought, 'what's that all about?' But it's become not only an iconic fight, it's an iconic moment in sport. Then there was Ali with Frazier, third fight, 'Thrilla in Manila'... So, it's nothing unusual.
"They are professional boxers; I'm not going to make any excuses about it. Would I like to see it, would all the fans like to see it at Wembley? Of course they would. But they're in the hands of another broadcaster who wants the fight in America."
