Usyk outpointed Joshua in London last September to take the belts from the Briton, who previously lost the gold to Andy Ruiz Jr in 2019.
Joshua, 32, avenged that shock stoppage loss by beating Ruiz Jr on points in Saudi Arabia, where his rematch with Usyk, 35, takes place this weekend.
To once again reclaim the titles, Joshua must do what no fighter has done during Usyk’s professional career and defeat the Ukrainian.
