Winner of Hrgovic v Dubois could become IBF heavyweight champion

The winner of Saturday's heavyweight fight between IBF mandatory challenger Filip Hrgovic and Daniel Dubois could become world champion if Oleksandr Usyk relinquishes the belt or is stripped by the sanctioning body.

The BBC quoted the IBF saying it "does not have a timeline as to when the decision will be made on Usyk's exception request."

The IBF has previously stripped champions of titles for failing to fight mandatory opponents, with Fury losing a heavyweight belt in December 2015, 10 days after he took it from Ukrainian Wladimir Klitschko.

Britain's Lennox Lewis was also stripped of the IBF heavyweight belt in 2002.

"Maybe the winner of that has AJ (Anthony Joshua) next in line for the IBF. You can't ignore your mandatory challenger for two or three years.
