The fighters hold all the titles between them — Fury is the current WBC champion and Usyk holds the WBA (Super), IBF, WBO and IBO belts. The winner will be able to call himself the ruler of the heavyweight division, but he will also have to defend that crown in short order as Fury says there is a rematch clause built into the contract.

Speaking to the DAZN Boxing Show in Saudi Arabia ahead of Friday's Anthony Joshua vs. Francis Ngannou showdown (also live on DAZN), Fury explained that the winner between himself and Usyk will take on the victor of Joshua vs. Ngannou — but not before a heavyweight title rematch is fought.

Fury claimed that he didn't want a rematch but Usyk insisted on it.

"We had this big argument this year, I don't know if you remember when I said 'no rematch clauses', but [Usyk] was acting like a little b— crying over a rematch," Fury said.

"He didn't want to just throw it down and whoever won, won, so he ends up getting his rematch clause."

With the first fight set for May 18, Fury said the wait for the second bout won't be long.

"There'll be two fights this year [between] me and Usyk, regardless of whatever happens in the first one."
