Usyk shut all of it down, thats why
Wilder also getting dragged by Fury also put the breaks on it.. and especially now dude is basically done. 
AJ can still get a Fury fight if he hasn’t checked out of existing in the boxing world (saw vids of he being shytfaced and carried out a bar after Usyk 

 ).
But AJ vs. Fury would be great to set up a big fight for Usyk. I still think Fury can beat Usyk though… if he doesn’t fukk around in the next fight. Idk if AJ got the boxing skills needed against Usyk.
A lot of these dudes need to be fighting each other though. Wilder is done imo… getting KO’d last fight, losing to Fury clearly affected his mental health.. which isn’t a shock. He’s probably not fighting another Top-5 heavyweight again… maybe not top 10. He could fight Ngannou though, that will sell and it could be a confidence boost if he wins.
