Tyson Fury's promoter Frank Warren has confirmed a third fight with Deontay Wilder is already in the books.
Fury and Wilder fought to a draw in their first fight in 2018 and are set to go toe-to-toe again in their rematch in February.
A two-way rematch clause has already been inserted, guaranteeing the trilogy regardless of the result in February.
And Warren has confirmed the pair will face off again in the summer of 2020.
"Tyson is going to be back in the ring with Wilder on February 22," he told talkSPORT.
“And they will fight again, irrespective of who wins, in the summer.
“So that, at the moment, is all tied up.”
The news means Anthony Joshua is likely to be made to wait before he can take on either of Fury or Wilder.
The Brit set his sights on becoming undisputed world heavyweight champion after winning his rematch with Andy Ruiz Jr.
Meanwhile, Fury has accepted Joshua's offer to spar him ahead of the rematch with Wilder.
Fury said: "I just saw a video of Joshua saying he'd love to come me in camp and that I'd fight him quicker than Wilder - that's for sure.
"When I beat Wilder I will fight you AJ no problem and I'd love to have you in camp.
"I'd really love to have you in camp for this fight and give Wilder a proper beating."I hope you mean it because I'd love to have you in training camp. Thanks very much and well done in your last fight, congratulations."
