IBF Gives Usyk One-Week Deadline
The International Boxing Federation (IBF) has issued a seven-day deadline to heavyweight champion Oleksandr Usyk, requiring him to confirm a defense of his IBF title against mandatory challenger Daniel Dubois or to vacate the belt. Failure to act within the period will result in the champion being stripped.
Recent Victory, Title Context
Usyk, 39, retained the WBC, IBF and WBA heavyweight crowns by stopping Dutch kickboxer-turned-boxer Rico Verhoeven in the 11th round of a bout held last Saturday. The victory followed his historic win over Tyson Fury that unified the division’s four major titles, making him the sport’s first undisputed champion in the four-belt era.
Key Figures & Data
Oleksandr Usyk (Ukrainian champion), Daniel Dubois (British IBF mandatory), Tyson Fury (potential rematch opponent), Agit Kabayel (WBC interim champion since February 2025), promoter Frank Warren, and the IBF are involved. Usyk holds three heavyweight belts; Kabayel’s interim title has been active since February 2025; Dubois is the IBF’s mandatory challenger.
Deadline Impact
If Usyk relinquishes the IBF belt, the heavyweight division could revert to multiple champions, undoing the undisputed status. The outcome will shape future marquee matchups, affect broadcast revenue, and influence the scheduling of high-profile events.
Official Statements
The IBF reiterated its policy that mandatory challengers must receive a title shot to keep championships active. Usyk’s camp has not issued a comment. Dubois’s promoters indicated readiness to fight, noting the mandatory status provides leverage. The IBF warned that exceptions to its rules are rare.
Criticism
Agit Kabayel, WBC interim champion, expressed doubt that Usyk will accept a fight with him, suggesting the Ukrainian champion is likely to vacate the belt rather than meet Kabayel’s demand.
Conflicts
Both the IBF’s seven-day mandate and Kabayel’s speculation refer to a one-week window, but only the IBF deadline carries procedural authority. No direct statement from Usyk or his representatives has been reported.
Verbatim Quote
> “To be honest, I think Oleksandr will vacate. I think Frank is talking about [the fight] with Usyk’s team, and we will wait one week. I think we have one week to see if Usyk says anything, after that we will see what [happens]. But my opinion is that Usyk will not want to make the fight for me. I want to fight with Usyk.” — Agit Kabayel, WBC interim champion
What’s Next
Usyk must either sign a contract to fight Dubois by the end of the week or relinquish the IBF title. If vacated, the IBF will order its top two contenders—likely Dubois versus Anthony Joshua or Filip Hrgovic—to contest the vacant championship, while Usyk may pursue a Fury rematch.
