What consequence does a team face if a player uses an unauthorized helmet?

When a player uses an unauthorized helmet, the team faces the consequence of having that player removed from the game. However, the key aspect of this situation is that the player can be replaced by a substitute, allowing the team to maintain their roster strength and continue to compete. This rule is in place to ensure player safety and adherence to regulations governing equipment, as unauthorized helmets may not meet the necessary safety standards.

The option indicating a warning for the player does not align with the strict enforcement of equipment regulations, which prioritize safety and compliance over leniency in such cases. Similarly, penalizing only the coach or penalizing the entire team with a loss of points does not accurately reflect the structure of penalties established in most sports related to unauthorized equipment use. Thus, the correct understanding is that the player must be removed, but their position can still be filled by a substitute, allowing the game to continue without major disruption to the team's strategy.
