I agree that the sports must be regulated or modified in a certain way to minimize the risk to the participants. It must be made mandatory that they must refrain from contact up to a certain age but also after a certain age injury of any kind must be avoided. Well, as a parent I would definitely not want my child to get hurt and that having some far reaching consequences in the later stage of his or her life. But the thing is that I can only control this thing till a certain point of time.
