Fury versus Usyk? I assume Anthony Joshua has lost? I did not follow anything about this fight and I have never read anything about the outcome of this until I read your post. In any case, Joshua showed some weaknesses versus Ruiz who he underestimated, I speculate he also underestimated Usyk or the British mafia is threatening him hehehe. This is a very strange inconsistency of performance for a very good boxer like him.
Nah, I don't think he underestimated Usyk. I think he was just bettered on the night. Now, I've heard that Joshua has activated the rematch clause, which is probably predictable. However, he has to be a lot better than he was the other night if he's to win against Usyk. Personally, I don't see it happening, and I expect a similar fight the second time around. It's a shame, and I do hope that Joshua vs Fury actually happens regardless, however it has definitely put a dampener on the fight because of it potentially never being a unification fight.
