What is the penalty for illegal use of a boot/stud on a player’s cleat?

The penalty for illegal use of a boot or stud on a player’s cleat is categorized as unsportsmanlike conduct, which carries a penalty of 15 yards. This ruling exists because the use of equipment that could potentially cause injury to another player is taken seriously in the sport, as safety is a top priority. When a player is found to be using illegal equipment, that action is deemed unsportsmanlike because it compromises the integrity of the game and the safety of the players involved.

The significant yardage penalty reflects the seriousness of the infraction and serves as a deterrent against such behavior. The other options do not accurately address the nature of the infraction; for instance, unnecessary roughness involves different kinds of physical play that endangers players, while options suggesting no penalty or a lesser penalty do not align with the NFHS's rules regarding equipment violations and player safety.
