Dr. Parekh, Rothman Orthopedics in New Jersey, formerly of Duke University, gives us his best assumption of what happened to Hamlin on the field and what caused it when looking at the hit? What other sports can something like this happen, with that kind of hit? Also, you might be surprised at what little effort it takes to have this impact; when considering this hit in particular didn’t look as harsh as some other hits we’ve seen in the NFL? How substantial was it that the emergency personal was able to get to him and start CPR as soon as they did? Assuming that there is no brain damage, are we talking about a career ending injury or is it possible for a full recovery to where Hamlin can play again?
