He said Tuesday at practice that he knocked in the head several times and has been complaining about headaches since then especially when he bends down. He said he had blurred vision eaelier today. He loves football and really wants to play on Saturday but I am concerned. This is his first year of playing football and he loves it, and wants to play through any small injuries, but I don't want it to be something to affect the rest of his life. Are there things I should be looking for in terms of a concussion? The coach set him out of practice on Wednesday but he practiced today when he said he was better, but is complaining about headaches again tonight.
