All eyes turn to London on Saturday, July 19, as Oleksandr Usyk and Daniel Dubois clash in a high-stakes rematch for the undisputed heavyweight crown.

Oleksandr Usyk attempts to get in Daniel Dubois' head one final time by stepping ahead of the Briton and standing at the front of the stage during the weigh-in at BoxPark Wembley.

Oleksandr Usyk is set to earn a reported $138M in his bout with British fighter Daniel Dubois, one of the largest purses in boxing history. Photos from Usyk's childhood and career chart his rise from an impoverished upbringing in Ukraine to his legendary status today.

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.

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.
