Players in high school football who are detected with missing or improperly worn equipment during playing action will be removed from the game for at least one down, unless the improper equipment is directly attributable to a foul by the opponent.
This revision in Rule 1-5-5 and other related rules was one of five rules changes for the 2018 season recommended by the National Federation of State High School Associations (NFHS) Football Rules Committee at its January 19-21 meeting in Indianapolis. All changes were subsequently approved by the NFHS Board of Directors.
Rule 1-5-5 also states that if the player is wearing otherwise legal equipment in an illegal manner, the participant must also be replaced for one down. If proper and legal equipment has become improperly worn through use during the game, and prompt repair does not delay the ready-for-play signal for more than 25 seconds, the repair can be made without replacing the player for one down.
In a related change (1-5-4), the head coach is responsible for verifying that all players are legally equipped and will not use illegal equipment. The penalty provisions for any use of illegal equipment remain unchanged and result in an unsportsmanlike foul charged to the head coach.
