A deal has been reached by both sides for a fight in Riyadh Saudi Arabia in March this year.
The card was confirmed by Saudi General Entertainment Authority chairman, Turki Al Alshaik, on social media.
The two heavyweights are expected to clash on March 8.
Anthony Joshua was initially scheduled to fight against Deontay Wilder on March 9 before the latter was upset in December’s bout against Joseph Parker.
Ngannou will face Joshua after making his boxing debut against Tyson Fury on October 28, in which he lost by a split decision.
Before the Ngannou-Joshua fight, Fury will meet Oleksandr Usyk on February 17 for the undisputed heavyweight championship. The winner may be set up for a future fight against the winner of the Ngannou-Joshua fight.
