Your question suggests the larger issue of whether a school district can be held responsible for injuries that a student sustains at school. Generally, the answer is no. As governmental entities, school districts enjoy certain immunities from civil claims for negligence. The law does provide exceptions to a school district's "sovereign immunity", but these exceptions do not typically apply in a gym setting. Based upon what you have described, the school district has no legal responsibility to pay your son's medical bills.
