The surgeon said the risk of the ball dying runs through the first year. He said there are a bunch of factors like bone fragments in the socket, the damage to the socket wall, the need to reposition the ball in the socket again which could disrupt blood flow.
The things mentioned in the article working in Tagovailoa's favor: top notch ortho hospital in Houston where top tier surgeons will be on the case and hip "reduction" (I guess that means getting the ball back into the socket quickly) was done on the field, and of course — youth.
I do not believe the ball will die and he will need his hip replaced like Bo Jackson. But I think there is a good chance that the shape of the socket will never be the same and arthritis will set in quickly.
