Tyson Fury has revealed his undisputed heavyweight showdown with Oleksandr Usyk is set to take place on December 23.

Fury and Usyk signed contracts last month for the eagerly-anticipated clash, which will take place in Riyadh and be the first undisputed contest in the blue riband division since Lennox Lewis beat Evander Holyfield at Madison Square Garden in 1999 when all the belts were on the line.
