Tyson Fury has insisted he will refuse to fight Oleksandr Usyk for the IBF heavyweight title - putting an undisputed fight in jeopardy.
The 'Gypsy King' has made a U-turn on his plans to retire and will return to action this weekend in a voluntary defence of his WBC title against Derek Chisora at the Tottenham Hotspur Stadium. A win is expected to set up an undisputed title clash with Usyk, who called out Fury following his rematch victory over Anthony Joshua in August.
Negotiations are ongoing for the potential showdown, despite suggestions the IBF could force the Ukrainian to instead take on mandatory challenger Filip Hrgovic - but Fury is not interested in fighting for the belt anyway.
