If a referee finds improper field conditions, which decision should they make?

The most appropriate decision for a referee faced with improper field conditions is to postpone the match. The safety and well-being of the players are of utmost importance in any sporting event, and if the field conditions could pose a risk to the players, taking immediate action is necessary. The referee is responsible for ensuring that the field meets the safety standards required for play.

Notifying both head coaches is important, but it does not address the issue of field safety directly. Simply starting the game while monitoring the situation could lead to potential injuries, as conditions may worsen and affect playability. Continuing with play as planned disregards the potential hazards presented by the field, which can have serious consequences for the players' safety.

Therefore, postponement is the best course of action to ensure that all players can compete safely and effectively.
