Usyk vacates IBF heavyweight title

Oleksandr Usyk has vacated the International Boxing Federation (IBF) heavyweight belt, the Ukrainian said on Tuesday, five weeks after becoming the undisputed heavyweight champion.

The announcement comes after Usyk's mandatory IBF title defence against challenger Croatian Filip Hrgovic was left pending and Daniel Dubois became the new interim IBF heavyweight champion by beating Hrgovic earlier this month.

The 37-year-old Usyk requested not to be stripped of his IBF belt to contest the undisputed champion title when he takes on Fury in their December rematch, where only the WBC, WBO and WBA titles will now be on the line.

The heavyweight IBF title, which Usyk held since 2021, will be up for grabs when Anthony Joshua takes on Dubois in September at Wembley Stadium.

"Anthony and Daniel, I know the IBF title is important to you. It is my present to you on 21 September," Usyk said in a video message on X.

Last month Usyk became the first undisputed heavyweight champion since 2000 as he claimed the WBC title by beating Tyson Fury by a split decision in Riyadh, Saudi Arabia.

Usyk said he may return to the cruiserweight division following his rematch with Fury.
