Joshua will fight Daniel Dubois in September 2024. Dubois holds the IBF belt and has stopped his last two opponents. The fight will be a big test for Joshua.
Fury, on the other hand, will try to get his belts back in a rematch with Oleksandr Usyk. They'll battle for three of the four major world titles. Fury wants to make up for his only loss.
If both Joshua and Fury win their fights, they could meet in the ring in 2025. The winner would become the undisputed heavyweight champion.
Wladimir Klitschko, who fought both men, thinks Joshua will win. He told The Sun:
"Hands down Joshua. He is getting to be the complete fighter. Technically, size-wise, weight-wise, power-wise. And he is a good learner."
Klitschko isn't as confident about Fury's chances:
"The other guy [Fury], like a fart in the wind it is there and it is gone. In the history of boxing there are a lot of examples of this kind of guy. They can be successful for a time but are not disciplined enough to continue to be successful. I wish Tyson well but I think there is a lack of discipline there, and discipline is more important than motivation."
Klitschko lost to Fury on points in 2015, which was a big upset. A year later, Joshua stopped Klitschko in a thrilling fight.
Joshua has lost three times in his career - once to Andy Ruiz Jr and twice to Oleksandr Usyk. Fury regained the heavyweight title and had an epic trilogy with Deontay Wilder before losing to Usyk.
The boxing world will watch closely as these two British stars try to climb back to the top of the heavyweight division.
