The Oleksandr Usyk vs. Daniel Dubois 2 fight card, start time is for Saturday's undisputed heavyweight championship showdown at Wembley Stadium in London. Usyk, the WBO, WBA, and WBC heavyweight titleholder faces the IBF heavyweight champ Dubois in a rematch for all of the titles.

Dubois was the beneficiary of this move by the IBF, picking up the interim title with a June 2024 stoppage of Filip Hrgovic and then being elevated to full champion after Usyk was stripped. Dubois then defended his title with a spectacular knockout of Anthony Joshua in Wembley Stadium.

Oleksandr Usyk will take on Daniel Dubois for the chance to become a two-time undisputed world champion - and his preparation may surprise many fans.
