Yes, we take tackle football off the table for HS athletes and below. And then replace it with flag football. It's cheaper for the school, safer for the kids and has the benefit of being more coed friendly (a necessity for small schools that struggle to find enough players).
Soccer is addressing the concussion issue by banning headers. I think the current rule is no headers for U12s and below. That will probably be adjusted upwards to U14s at some point.
