Daniel Dubois and Oleksandr Usyk will fight to become the undisputed world heavyweight champion at Wembley Stadium on 19th July, 2025.
British boxer, Dubois is the IBF champion, while Usyk holds the WBA (Super), WBO and WBC belts.
Usyk is also undefeated in 23 fights and defeated Dubois, 27, via a ninth-round stoppage the last time they met in August 2023.
The 38-year-old Ukrainian made history in May 2024 when he beat Tyson Fury to become the first undisputed heavyweight champion of the four-belt era.
Usyk, who was also undisputed at cruiserweight, vacated the IBF belt prior to his rematch with Fury in December.
Dubois was became the IBF champion as a result and successfully defended the belt against Anthony Joshua last September.
He was set to make a second defence against Joseph Parker in February but illness forced him to withdraw from the bout in fight week.
No British boxer has held the undisputed heavyweight title in the four-belt era, and the last Briton to be undisputed heavyweight champion was Lennox Lewis in 1999.
The last time Usyk was involved in a bout in the ring was back in December when he earned a second win against Fury.
