David Haye has questioned the validity of an announcement from Tyson Fury's uncle and trainer, Peter Fury, that he will fight Wladimir Klitschko in a world heavyweight title rematch in the champion's home city of Manchester.
Fury dethroned the long-time king of the heavyweight division in a shock victory last November to win the WBA, WBO and IBF heavyweight titles.
Klitschko has exercised his right to a rematch, but the duo struggled to agree on a date and a venue for the fight.
It appeared as though a compromise had been reached when Peter Fury took to Twitter on Friday to announce a bout in Manchester on July 9.
However, fellow Brit Haye told fans not to book their tickets just yet as he believes it was a mere PR stunt to detract attention away from Anthony Joshua's world title fight against Charles Martin on Saturday.
"I don't see that [a fight in Manchester] happening, someone in Klitschko's camp said it was happening in Germany literally a few days ago," Haye told Omnisport. "I wouldn't pay too much attention to that.
"Until it's officially announced I wouldn't start booking your tickets to Manchester just yet. Who knows [why Peter Fury made the announcement]?
"His comments have come on the same day as the press conference [for Joshua's fight], they had the weigh-in here.
"Maybe there's a lot of noise about Anthony Joshua and not so much about the Klitschko rematch and to try to keep the Tyson brand out there they make an announcement of some sort. It's an announcement of an announcement.
"You see it happen all the time, I understand it but at the moment this [Joshua-Martin] is the fight everyone is interested in."
Joshua gets his world title opportunity despite having just 15 fights, albeit all of them resulting in knockout wins, but Haye does not expect his fellow Brit to offer him a shot at the title should he see off Martin.
"He's [Joshua] not going to fight me straight after this, he's not stupid," he added. "He'll have the chance to face some voluntaries so I expect him to maximise those opportunities to the fullest.
"He'll get a bit more experience, the experience that people said he needed before this fight he will get after this fight, I understand it."
