I have always feared that there might be psychological problems running on from this incident. He's 23 lying on the ground for 20 minutes or whatever with no feeling below his neck.
It's one hell of a scare, so can he play with the same intensity in the future?
On the other hand, he might be thinking enough is enough and as there isn't adequate protection from L1 refs, sod it, I'm off.
I wouldn't blame him.
