Exactly. My sister has two boys (I have two girls who both do karate and one is a black belt) who play hockey and football. The older one got a concussion playing hockey and missed a couple weeks of school. They both still play but she is definitely not “comfortable” with it exactly because of the concussion issue.
Far more kids die or get critically injured in MVA's yet no one bats an eye. Yes I'm a parent who has received one of those calls. I went to the scene of the wreck as they started cutting my daughter out. Six months later after the surgeries etc she was driving again.
