Yes . He clearly quit in the Joyce and Usyk fights. Showed heart we'd never seen from him before though in the Hrgovic and Miller fights.
Nope, he's packing glass. Sometimes when a fragile mandible shatters, it looks like quitting, but the root cause is found in that chinny chin CHIN!!
If he fought on against Joyce he probably would have had his career ended early. It was the right decision the fight was already lost. Usyk fight was exhaustion TKO
Dunno. He showed good heart in every other fight so I'm inclined to believe he was injured against Joyce.
Well he's quit before so he does have that quit in him but give credit where it's due, last 2 fights he's shown some robustness to carry on.
He suffered a very serious eye injury against Big Joe Joyce You can argue that he did a quit against Usyk and regardless if you believe that or not, I personally like to because the two ultimate methods of victory are 1. JTFO KO (jab the [expletive] out knockout) and 2. No mas And Usyk is the only man in the history of the sport to simultaneously score a JTFO KO and a no mas win which he obviously did in that fight.
In the Joyce fight, he did the right thing. Only an imbecile thinks he should continue and permantly damage his eye.
