BBC Sport looks at the numbers behind Daniel Dubois' first meeting with Oleksandr Usyk and what he has been doing to prepare for the rematch on Saturday.

Dubois was routinely feinted out of position by Usyk in the first fight, forced into compromised positions. Usyk saw the patterns quickly: After Dubois would throw, he often would reset his position and stance with a subtle bounce in place, a rhythmic tell that became a green light signal for Usyk to counter.

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.

How much prize money will both fighters be paid? - Figures are much, much higher than first fight with undisputed heavyweight champion status on the line at Wembley

While other aspects of his boxing game may still need a polish, there is one thing for sure – Daniel Dubois packs a wallop. The hulking Londoner has been knocking men out for savage fun since he got started in the sport with  21 of his 22 professional victories ending before the final bell.
