Based on this fact set, I'd say yes, this was a HIPAA violation, unless one of the parents consented to sharing this information with the coach and athletic director. It's also possible that as part of allowing their son to play football, they signed a release or consent that would allow that information to be shared. If they did not, they can file a complaint with the health care facility/doctor in this situation or directly with the US Department of Health and Human Services.
