Your son doesn't play football does he? I'm glad mine quit after the 7th grade. He only had 2 concussion type hits. After the second one, he decided he was done with football. Two of his friends at Green have been knocked out cold this season and had to be carried off on a backboard and take an ambulance ride to the ER. Luckily neither one suffered a serious neck injury. Both are done for the season and their parents are happy they don't have to worry anymore.
