I read the injuries as a stress fracture and a chipped bone. I have experienced a stress fracture. It was no worse than a sprained ankle. Since I had sprained my ankle when it happened and I couldn't tell the difference. The chip is probably more annoying than painful.
I am sure it hurts, a lot. But if he can play on a badly sprained ankle, he probably can play with this.
But with the limited range on his arm and the loss of mobility added to a poor performance this year, they may be better off with T-Jack.
I want to go out like my Grandpa did. Peacefully in his sleep.
Not screaming in terror like his passengers.
