He is in an induced coma yer.
Apparently they wanted to bring him out of it, but after CT scans came back the condition of his brain wasn't great still.
Its still a bloody long time to be in a coma for, regardless of it being induced or not. I think the doctors said something like "If he can still walk and dress himself that would be a major victory".
Chances are, at the very best hes gonna have to learn to walk again and do a whole bunch of other stuff like that. Worst case? vegetable.
My question is, he hit his head on a rock, and he had a helmet on right? I guess helmets aren't designed to take the impact of a rock :/
Yes is spelt yes, not yer.
Also - your question is completely retarded.
