Joshua's team still hopes they can manage to make the unification fight with Tyson Fury (30-0-1, 21 KOs) scheduled for August 14, but if King of the Gypsies chooses the trilogy with Deontay Wilder (42-1-1, 41 KOs), AJ crosses gloves with Usyk.
Alexander Usyk has been a mandatory contender for Anthony Joshua's WBO belt since his transition to the heavyweights.
