Tyson Fury would only be tempted to come out of retirement for two fights, Top Rank president Todd DuBoef has claimed. Fury has been retired since retaining his WBC heavyweight title in April with a stoppage victory over Dillian Whyte at Wembley Stadium.

“Maybe the winner, when that fight happens, can pull him out, or maybe something else can be motivational like Ngannou. We saw Francis Ngannou get in the ring and it was kind of bizarre that the guy was retiring but the MMA heavyweight champion was getting in the ring to talk smack – which one are we doing here?

“But is it going to be he just sits in the South of France on the beach there and enjoys it? That again, I am speaking for him and that is a difficult position for me to be in to speak on what his feelings are.”

The fight with Ngannou came very much out of the blue and has already been verbally agreed. Minutes after announcing his retirement after the Whyte fight in his BT Sport interview, Fury called Ngannou into the ring for his ESPN interview to talk up a future fight after the pair had traded barbs on social media.

“This is going to be one very special fight,” Fury told ESPN in the ring after his win. “It’ll be something never before seen in the history of our sport. We’re not talking two guys around 140lb, I’m 270lb, he’s 270lb. It’s going to be an explosive fight when it happens.

“I’m the boxing heavyweight champion, he’s the UFC heavyweight champion, he’s in great shape, look at the muscles on him,” Fury continued. Ngannou added: “We are going to find out who is the baddest motherf***er on the planet,” to which Fury replied, “good man Francis”.

Usyk and Joshua are set to face each other on July 23 in Saudi Arabia for the WBA ‘super’, IBF and WBO heavyweight titles. Should WBC champion Fury choose to fight the winner then they would be competing in the first undisputed unification heavyweight bout during the four-belt era.
