This athletic management case involves a sixteen-year-old female student who was participating in a varsity field hockey practice. The student was not wearing her protective mouthpiece during the practice, even though she had it with her that day and knew that she was supposed to wear it. Half an hour into practice, the student was struck in the mouth by a field hockey stick swung by a fellow student. She suffered severe injuries to her mouth, including dental fractures and several broken teeth. The hockey coach never gave the student any specific safety instructions to the student about the mouthpiece and failed to explain the risks involved with not wearing the mouthpiece. The student’s parents sued the school district claiming that they were negligent in not properly supervising the hockey practice and failing to advise the students about the dangers of not wearing safety equipment.
