The numbers behind the Usyk and Dubois rematch
Oleksandr Usyk faces a potential IBF mandatory defense against Agit Kabayel that could delay a high-stakes rematch against Daniel Dubois at Wembley Stadium. Frank Warren aims to replicate the 96,000-person crowd seen during Dubois's previous major victory.
Mandatory challenges and title rules
Oleksandr Usyk holds the WBC, WBA Super, and IBF heavyweight titles. He has not fought for ten months since his July 2025 victory over Daniel Dubois. The IBF board of directors met via video conference to approve an exception for Usyk to fight Rico Verhoeven, but they will order a mandatory defense within 180 days if the Ukrainian wins his fight in Giza. This rule complicates the rematch against Dubois at Wembley Stadium. The IBF will enforce its mandatory next after the WBC position in the sanctioning rotation. I find the IBF’s rigid adherence to rotation rules a bureaucratic mess that threatens the stability of the heavyweight division. The IBF granted the exception because the fight in Giza falls outside the standard sanctioning framework used by the major heavyweight boxing organizations. If Usyk loses to Verhoeven, the IBF title becomes vacant immediately. The heavyweight legend Rico Verhoeven is 6 feet 5 inches and 270 pounds. Usyk remains undefeated with a record of 24-0 and 15 knockouts.
Dubois and the Wembley push
Daniel Dubois holds the WBO heavyweight title after his victory over Fabio Wardley. He stopped Wardley in the 11th round on May 9, 2026, at the Co-op Live Arena in Manchester. Wardley dropped Dubois twice in the opening rounds, once in the first ten seconds and once in the third, but the 27-year-old recovered to win. Dubois has a record of 23-3 with 22 knockouts. Frank Warren wants to host the rematch against Usyk at Wembley Stadium. He wants to replicate the 96,000 fans who saw Dubois knock out Anthony Joshua in September 2024. You should understand that Dubois needs this fight to solidify his status. He told reporters at a press conference in London that he wants to "be the man" when they meet.
| Fighter | Record | KOs | Age |
|---|---|---|---|
| Oleksandr Usyk | 24-0 | 15 | 38 |
| Daniel Dubois | 23-3 | 22 | 27 |
Dubois’s victory over Wardley was the heavyweight fight of 2026. Wardley caused heavy bleeding from the bridge of his nose before the referee stopped the fight in the 11th round. This win follows the fifth-round knockout of Anthony Joshua. That fight drew a record post-war crowd in Britain. Since he was 7 years old, Dubois has been boxing. Dubois lost his previous attempt at the undisputed title in Wroclaw, Poland, last year. That fight ended in a ninth-round stoppage for Usyk following a disputed low blow. During that previous fight, Dubois suffered an orbital bone fracture and nerve damage to his left eye.
Comparing the contenders
The statistical gap between the two fighters is clear. Usyk is 38 years old, while Dubois is 27. Dubois faces a massive task against a fighter who beat Tyson Fury in May 2024. The IBF mandate for Agit Kabayel looms over the schedule. If Usyk honors the mandatory, the Wembley fight might face delays. I see the promoter’s plan to use Wembley as a way to maximize the gate for this high-stakes rematch. Anthony Joshua, who lost to Dubois, has a record of 28-4 with 26 knockouts. Usyk is 11 years older than Dubois. Dubois previously held the IBF title after Usyk relinquished it to focus on a Tyson Fury rematch. Dubois’s career includes a loss to Joe Joyce in November 2020, where he was counted out in the 10th round. He recovered from that loss to win four straight bouts. Usyk, the WBA, WBC, and WBO champion, became the undisputed heavyweight champion after beating Fury in May 2024. The rematch in Poland was controversial because the referee ruled a fifth-round blow a low blow, which gave Usyk time to recover. Dubois must improve his mental attitude and avoid getting careless to succeed. Will the IBF allow the rematch to proceed without forcing Usyk to fight Kabayel first?
