Ring, WBC, WBO, WBA, IBO heavyweight champion Oleksandr Usyk expects his division rival, Tyson Fury, to come out of retirement at some point.
Fury lost back to back decisions to Usyk, with the most recent defeat taking place last December in Riyadh, Saudi Arabia.
Last month, Fury announced his retirement from the sport.
"Hi everybody, I'll make this short and sweet, I'd like to announce my retirement from boxing, I've loved every single minute of it," Fury said. “I'm going to end with this: Dick Turpin wore a mask. God bless everybody, I'll see you on the other side."
It wasn't the first time where Fury vowed to walk away from boxing - only to reverse his decision and return to the ring. Fury announced his retirement on at least three other occasions.
Usyk is predicting more of the same.
"I don't think about it but I think it is not true," Usyk told Talk Sport. "Once Tyson has relaxed, and rested, maybe Tyson will be back. Boxing if you do this for a long time: 10, 15, 20, 25 years then boxing is like a drug. If you don't go to training one day then you feel dead. For me, at least.
"I train every day. I don't do boxing every day. Sometimes I do crossfit, and running training. I only do boxing when I am in my camp."
