The correct answer to this question is "Then we'll find out the universe is being controlled by a chunk of Green Playdoh hiding inside a bank vault in Bozeman, Montana and the world is indeed flat after all..." About as likely....
Usyk will be forced to fight Wilder and get KO'd by skinny legs and we'll see the riveting Fury vs Wilder 4
It's very possible to see Usyk stoned on the canvas after a Wilder's punch, but even if that happens, I doubt we'll see Fury-Wilder 4, thus no unification will happen.
If they don't give Fury his 1 billion dollars then he rightfully should let his dosser Wilder do the dirty work for him. Then give him a slap to put him back in line.
