His past injuries were football threatening not life threatening. They won't rush him back until he is 100% healed.
He was reckless with his life riding a motorcycle without a helmet and his accident on that bike WAS life threatening. He said he could've died and he was lucky that an EMT quickly noticed the massive amount of blood that he was swallowing into his stomach.
But my point is that he now has a lot more to think about in making a decision on when/how fast to come back.
