The Associate State Veterinarian shall be present in the paddock before each race, and he shall inspect each entrant pursuant to specific veterinary medical procedures established by the State Veterinarian as approved by the Racing Commission. If, in his opinion, any entrant is not in condition to compete in that race, he shall immediately notify the stewards, who shall order the horse scratched out of the race. The horse automatically goes on the veterinarians list, and thereafter shall not be permitted to enter until the veterinarian notifies the racing secretary that the horse is again fit to compete.
