This won't happen. Jones has mediocre hands even by MMA standards and his ego is too big to step in the boxing ring and get beat up.
This but also I really doubt Dana would let this happen since Jones is still under UFC contract and it seems Dana/Hunter doesn't let this kind of crossovers happens
Didn't the UFC allegedly offer Jones thirty million to fight Aspinall? If that's true, that's an unprecedented payday for an MMA fighter. And, honestly, after everything he's accomplished, losing that fight wouldn't even really hurt his legacy. People would say that Jones was old. They would say that he was never a natural heavyweight anyway. Even though most MMA fans passionately dislike Jones and would take pleasure in his defeat, I think most people would be rational about the whole thing. Yet Jones still reportedly turned it down. I honestly think Jones is just done with fighting entirely at this point.
Also, if this is true and Usyk is just fishing for lucrative crossover fights at this point, can we at least give us the Rico rematch instead of this crap? As others said, boxing was always Jones' one real weakness as an MMA fighter. Nobody cares about this. But a Rico rematch would at least be somewhat interesting. Obviously, I think Usyk would do much better and finish the fight sooner, but at least there is some reason for him to right the "wrong". If Usyk doesn't think he can beat Rico again, then he shouldn't be fighting at all at this point.
