What is the ruling if a player wears a skull cap while playing?

The ruling states that wearing a skull cap is legal for defensive players as long as the cap does not have a glare. This is in line with specific guidelines that allow certain headgear for players on defense, provided it does not interfere with safety or visibility concerns. The focus here is on the player's position and the potential impact of the equipment on gameplay.

In comparison, the other options involve restrictions that do not pertain to the accepted regulations for headgear in this scenario. For instance, the requirement for dual earflaps or state association approval might apply to other forms of headgear, like helmets, but not to a skull cap that meets the defined criteria. Hence, the allowance of a non-glare skull cap for defensive players aligns with the rules in the NFHS guideline.
