Arum is not sure of what he is saying, he only said based on what he saw with a boxer's experience in the past. Yes, Arum is not a doctor, we should not believe in him but let us also understand that when you have a problem in your eye, some doctors would recommend you should not engage with combat sports anymore.
Sugar Ray Leonard got a detached retina and got surgery and this was 1982 he eventually came back to beat Hagler, coming from Sugar Ray
Now, we’ll wait to see how patient that Spence will be before trying to return.
I don't think Spence cannot come back because of the detached retina the technology is better now he survived the car accident he will survive this detached retina, there's still a lot of store for Spence, his career is not yet over far from over.
Let's be positive that he will be able to come back but we should also not neglect the possibility that he will not be able to play again. That was a sensitive condition and even if it heals already it will never be normal and it will be weaker, and if that is injured, you know the problem could worsen.
Don't get me wrong, I'm just concerned with this condition too as we know our eyes are very important.
