So I try to research about deaths of boxer inside the ring,
https://en.wikipedia.org/wiki/List_of_deaths_due_to_injuries_sustained_in_boxingAnd i guess this is what the rounds was readjusted in the 80's. Before boxers fought at 15 brutal rounds but was reduced to the standard that we are using today at 12 rounds.
The infamous fight that comes to my mind is Mancini vs Duk Koo Kim who collapsed in the ring and die. Then after several months the one that referee the fight committed suicide and so is Kim's mother. And it still haunts Mancini up to this day.
Did he literally died inside the ring? I mean dead on the spot?
AFAIK, boxers or fighters from different types of combat sports don't really die inside the ring, but will brought to the hospital first and then eventually die.
Fighters however already knew this might happen to them, especially when they're hit somewhere that'll put them in a comatose state.
If luckily they survive the heavy punishment all throughout their fighting career. Side effects will eventually surface once they're getting older and older.
Of course you don't have to take it literally that the die inside the ring. But most likely they have been damage already that the moment medical personnel is called, they could have been bleeding inside or there is blood clot already.
Risk is there, maybe this is one case of freak accident, that he was literally hit so hard that he got brain trauma from the amount of punches he received in that fight. Muhammad Ali is another good case, he didn't die in the ring, but we can surely see the ill effects on him.
I also don't know if there are some instances that the fighter or boxer died in the middle of the fight or even after the fight, what I heard was that they are taken to hospital at first to examine the damage further. Some have gone coma or worse died afterwards, most cases are because of head injuries sustained from the fight.

There's no evidence that boxing was the major contributor on what happened to Ali, he was just diagnosed with Parkinson's disease.
