Wow! Just in the last year my son had his hand broke and my daughter her arm broke both while wrestling and never in my mind did I consider suing the parents of the kids they were wrestling! As I recall also I signed something that stated that this was a contact sport that may cause injury and the liability was on myself and the usa wrestling insurance. That was the kids club. With HS you sign a form that your insurance covers 1st then the school has coverage. Shouldn't they have to go through the first 2 before they ask for anything from you? Which IMO they shouldn't because you know that every time your kid steps on the mat that there is the possibility of injury.
