Tyson Fury will not fight for Undisputed this year and will take on Cameroon's Francis Ngannou.
Francis Ngannou, a former UFC champion, will face Tyson Fury in his upcoming bout on October 28 in Riyadh, Saudi Arabia.
Since Ngannou joined Fury in the ring after the WBC heavyweight champion's knockout victory over Dillian Whyte at Wembley Stadium last April, there has been talk of a crossover fight between the two.
Three judges will be at ringside, using the 10-point must system, as the fight to determine who is the "Baddest Man on the Planet" will follow the regulations of professional boxing.
Tyson Fury vs Francis Ngannou
Ngannou and Fury announced the fight in a video on their official social media platforms.
Following his convincing victory against Derek Chisora in December of last year, Fury returns to the ring, but it is uncertain if his WBC world title will be on the line.
Since leaving the UFC after his contract expired, Ngannou signed an unprecedented mega-deal as a global strategic partner with the Professional Fighters League (PFL) and has had time to get ready for the fight against Fury.
The fight between Ngannou and Fury means that there will be no unification in the heavyweight division.
Usyk, a Ukrainian, had hoped to fight Fury in December but is scheduled to defend his championship against WBA mandatory challenger Daniel Dubois in August.
