Anthony Joshua's promoter, Eddie Hearn, also questioned if Tyson Fury would be ready in time for his rematch with WBC champ Deontay Wilder.
Tyson Fury has turned his attention to Deontay Wilder after his win against Otto Wallin and said he is "ready for war" with the WBC champ.
Otto Wallin has been branded a 'cheat' and 'incredibly dirty' in his attempt to inflict maximum damage on Tyson Fury's cut in their bout.
