Should a School Pay the Medical Bills of an Injured Student Athlete

My daughter received a concussion by being hit by a team mates tennis racquet. This was on the court during practice before a game. The tennis coach was not supervising the players. Now she has been unable to play for 10 days and she is taking concussion test at school. The technician says her tests are getting worse. We did not know about the worsening tests until yesterday. The technician never told us and my daughter thought everything was getting better. Now the technician wants us to take her to the doctor. I believe this is the right then to do but I believe the school should pay for the doctor visit. The school did not handle this well. Their was poor supervision and not communication after the fact. Do I have any leg to stand on for doctor compensation fees? It is a public school.

Thanks
