In the 3rd fight it can be argued that the count was slow and Fury should have been counted out, but it doesn't matter. We all know Fury wins that fight 9/10, and we all know Wilder always has a punchers chance, same with Dubois. Usyk would have won the rematch anyway. Dubois had a punchers chance, and if he had won there'd have been a rematch and Usyk 9/10 wins it. So it would be a waste of time, and just delay a better fight from happening. Usyk has already beaten far better than Dubois. Usyk schooled Dubois for the rest of the fight anyway, and got up and won. I personally think it was a low blow, as from the angles I've seen, Dubois glove is almost touching Usyk's willy.
