Usyk vs. Kabayel: WBC Mandates Title Defense After Voluntary Fight
6/2/2026, 4:34:43 AM
The WBC’s Mandatory Order
The World Boxing Council has ordered unified heavyweight champion Oleksandr Usyk to defend his WBC title against interim champion Agit Kabayel. President Mauricio Sulaimán warned that failure to meet the mandate could result in Usyk being stripped of the belt, even though he retains the WBA Super and IBF titles.
Background: From Voluntary Defense to Mandatory Obligation
Usyk’s most recent bout was a voluntary defense against kick-boxer Rico Verhoeven in Egypt on 23 May 2025. The WBC approved that fight, but the organization now insists the next defense must honor the mandatory challenger system, which places Kabayel directly in line.
Key Figures
- Oleksandr Usyk – Ukrainian, undefeated, holder of the WBA Super, WBC and IBF heavyweight titles; vacated the WBO belt in November 2025.
- Agit Kabayel – German, 27-0 with 19 knockouts, interim WBC heavyweight champion since February 2025; notable wins over Zhilei Zhang and Frank Sanchez.
- Mauricio Sulaimán – President of the WBC, responsible for enforcing the mandatory challenger rules.
Data & Statistics
- Kabayel’s record: 27 wins, 0 losses, 19 KOs.
- Usyk holds three of the four major belts; the WBO title was relinquished in Nov 2025.
- Timeline: Feb 2025 – Kabayel becomes interim champion; 23 May 2025 – Usyk defeats Verhoeven; Nov 2025 – Usyk vacates WBO; June 2025 – WBC issues mandatory order.
Official Statements & Responses
Sulaimán emphasized that the ruling is “very clear” and that the WBC “expects Oleksandr to honor the rules.” He added the organization “doesn’t anticipate, doesn’t speculate” and will act only after a formal proposal is presented. Kabayel’s camp has publicly stated the contender “wants to fight with Usyk,” underscoring the pressure to honor the mandatory pathway. The WBC reiterated that its challenger system is designed to give deserving contenders a title opportunity.
Criticism & Opposition
Referee Mark Lyson faced criticism for stopping the Verhoeven fight with seconds remaining in the eleventh round. Sulaimán defended the decision, asserting that the referee’s “only concern is the safety of the fighter” and that “he’s not a timekeeper, he’s a lifekeeper.” Some analysts and fans have called for an immediate rematch with Verhoeven, but the WBC has ruled that such a bout is not permissible under the current mandate.
Conflicting Reports & Gaps
It remains unclear whether Kabayel would be elevated to full WBC champion if Usyk is stripped, or if the belt would be declared vacant and contested. The WBC has not disclosed a specific deadline for negotiations, nor have purse-share terms been made public.
