Wife wants son to give up a sport he loves. I want it to be his decision. Looking for advice. (X-posted)

My wife has never wanted our son to play football. She is a surgeon (though not a brain surgeon) and is aware of the issues relating to concussions. We had originally agreed to not allow our son (or daughter) to play tackle football.Our son asked again when he started middle school and after much consideration, we decided to allow it. He was beaming after the first game and we knew that he loved being out there. We continued to allow it despite our fears because it made our boy so happy and we saw him become more confident.It may be important to note that our son is very small for his age. He is in 7th grade and is just under 4'7 and weighs around 74 pounds or so. He plays bigger than he is and gives it 110 percent. This has resulted in some injuries, one of which was a concussion that happened about a month ago. Our son is back into action and seems to be fully recovered.With new information coming out about CTE seemingly every month, my wife has become more concerned. The news that Aaron Hernandez's brain was similar to that of a 60 year old man with CTE seemed to be the last straw and she said that she doesn't want him playing football next year. I see her concerns, but I don't want to stop my son from doing something he clearly loves. He wrestles and plays baseball as well, but football is his passion. He will be crushed if forced to give it up.Am I being unreasonable for wanting this to be his decision? Should I just accept that this is too risky and talk to my son about it? My wife said he can continue this year because he made a commitment to his team, but doesn't want him playing next year. He'll be 13 by then. Any tips on how to tell a 13 year old that we are making him give up the sport that he loves most? via /r/Parenting http://ift.tt/2xoaeR3
