What should the referee do if the assistant referee signals for an illegal hold?

When the assistant referee signals for an illegal hold, the appropriate action for the main referee is to enforce the ruling as indicated by the assistant. This ensures that the integrity of the match is maintained and that all regulations are followed according to the rules governing wrestling. The assistant referee’s signal serves as an important alert regarding a possible violation that could affect the safety and fairness of the competition.

By enforcing the ruling, the referee acknowledges the assistant's role and expertise, fostering teamwork on the officiating crew. It helps to uphold the standards of the sport, ensuring that the participants adhere to the rules and that the match is conducted fairly. This collaborative approach is essential in maintaining the safety of the wrestlers and preserving the integrity of the match and the sport overall.
