Anthony Joshua and Daniel Dubois are set to clash in an all-British bout for the IBF heavyweight title on September 21 at Wembley Stadium. This match follows Oleksandr Usyk’s decision to vacate the world title. Dubois, who was the IBF’s mandatory challenger, has been promoted to champion following Usyk's vacating of the belt. This development means that Usyk is no longer the undisputed world heavyweight champion.
