Anthony Joshua has been challenged by Deontay Wilder's manager for a heavyweight clash even if he loses to Oleksandr Usyk.
Both Joshua and Wilder have reached a difficult period in their careers, with Wilder suffering back-to-back defeats to Tyson Fury to lose his WBC heavyweight belt and has since been surrounded by retirement speculation.
Joshua, meanwhile, lost his three heavyweight belts in September to Oleksandr Usyk in a devastating fashion and a second defeat to the Ukrainian in the pair's upcoming rematch may also see him face similar questions.
