"Taking an injury time-out for a non-injury situation is unethical." However, it doesn't prescribe a penalty for that
A wrestler should not have the ability to dictate the outcome of a bout by calling for injury time as he/she is about to be pinned/lose a bout. The official should award point/points to the wrestler who just got his pin/back points taken away. A wrestler should not have the ability to call for injury time stoppage MULTIPLE TIMES in a tournament. You know who you are.
