I didn't see it but it makes me cringe just thinking about it. At a high school basketball game last night. Kid went up to try and block a shot. Very athletic kid. Listed at 6'3". He was so high it looked like his head was almost even with the rim. the kid he was trying to block didn't go up for the shot. He only faked the shot and the blockers momentum carried him into the kid on the ground. Cut he legs out from under him and the first thing that hit the floor was the back of his head. He didn't move for a few minutes. Called an ambulance and took him to the hospital. Probably had a concussion. They did a CAT scan but I don't know the results yet.
