In case of serious injury to a contestant, the Commission may conduct an investigation to determine if there has been a violation of this chapter on the part of any person.
The examining physician shall attend to the contestants at the immediate ringside until the conclusion of the final contest on a program.
After the final contest on a program the examining physician shall go to the dressing room and ascertain whether any contestant has been injured in the ring. If so, the physician shall ensure that the contestant receives the necessary medical treatment.
Before engaging in any contest each contestant shall be physically examined at a time and place designated by the Commission by a licensed physician appointed by the Commission. An inspector shall ensure that all contestants comply with this requirement.
No contestant may take part in an event without the approval of a licensed physician appointed by the Commission. The physician shall certify the facts of the physical examination.
The Commission may revoke or take other action against a contestant's license if it finds that the contestant, at any time before or during an event, has used any drug, alcohol, or stimulant that alters the physical or mental state or the performance of a contestant.
