Tyson Fury and Oleksandr Usyk have agreed to fight each other next in a world heavyweight title unification showdown, according to promoter Bob Arum.

Fury beat his old British rival Derek Chisora to retain his WBC belt earlier this month and immediately called out Ukrainian Usyk, who holds the IBF, IBO, WBO and WBA titles and was ringside at the Tottenham Hotspur Stadium.
