Tyson Fury and Oleksandr Usyk will fight for the undisputed heavyweight championship of the world in Riyadh on February 17th, organisers announced on Thursday.
Britain's Fury is the WBC world champion while Ukrainian Usyk holds the WBA, WBO, IBF and IBO belts. Both have unbeaten records.
Contracts were signed in September for a proposed December 23rd date, although that was never confirmed and slid after Fury's near defeat to former UFC champion Francis Ngannou in a non-title bout in Saudi Arabia on October 28th.
Heavyweight boxing's last undisputed world champion was Britain's Lennox Lewis in 1999.
