What's new and emphasized for high school varsity football officials (grades 9-12) in 2026? Rule changes, points of emphasis, equipment, recent fouls and enforcement, lightning and concussion procedures.
High school games in states that adopt NFHS rules are played under the 2026 NFHS Football Rules Book.
The rules book also covers the rules differences for 6-, 8- and 9-player football.
Two playing-rule changes, plus one equipment rule taking effect:
There were also editorial changes to several rules and to the official signals.
The NFHS Football Rules Committee named four for 2026:
The head coach must verify before every game that all players are legally equipped and will wear the equipment properly. Allowing illegal or improperly worn equipment can result in a penalty against the coach.
Illegal equipment examples: jewelry, tinted visors, non-compliant eye shade, bands on the upper arm, neck or legs, and non-conforming adornments such as towels. Player-worn cameras and microphones are also illegal.
Improperly worn equipment is legal gear not worn as intended, for example:
New for 2026: tooth and mouth protectors can't include attachments that don't protect the teeth or mouth, or anything that's a health or safety risk to the wearer or others (Rule 1-5-1d(5)).
Player-worn devices (Rule 1-5-3c(3)): any video (camera) or audio (microphone) device worn by a player during the game is illegal equipment.
Electronic signs (Rule 1-5-3c(2)): fixed, non-audio electronic signs that display play signals may be used to communicate from the sideline. Scrolling graphics, video footage and connected audio are illegal, in-helmet communication remains illegal, and players between the numbers still can't watch video.
Play cards (Rule 1-5-3c(9), new for 2026): may be worn on the forearm/wrist or on the belt.
Rule 9-4-3p (added in 2025): no player or non-player may initiate forceful contact against a defenseless receiver, unless the contact is:
Penalty: personal foul, 15 yards. A flagrant foul also disqualifies the player.
Defenseless players include passers, receivers, sliding runners and players blocked illegally from the blind side. A player stays defenseless until able to protect themselves. Defenseless player and targeting fouls were a 2025 point of emphasis, and flagrant fouls are a 2026 point of emphasis.
Since the 2025 revision of Rule 9-6 (and deletion of 10-4-4b), all illegal participation fouls are 15 yards, enforced as a live-ball foul from the basic spot.
The committee's aim is consistent enforcement, so a team can never gain an advantage by having a player enter and take part in a play illegally.
Since 2025 (Rules 3-4-2d, 3-4-3a, 4-3-1 exception):
| Situation | Spot | Game clock starts |
|---|---|---|
| Forward fumble out of bounds between the goal lines | Returned to the spot of the fumble | On the ready-for-play |
| Forward fumble into Team B's end zone, ruled out of bounds | Not returned: touchback | — |
| Backward fumble out of bounds between the goal lines | Where it went out of bounds | On the snap |
| Forward muff out of bounds | Where it went out of bounds (the exception doesn't apply) | On the snap |
Under Rule 1-5-1b(3), all home team jerseys must be the same dark color(s) that clearly contrast with white. Illegal home jerseys were a 2025 rules reminder.
Since 2025, a school mascot is an allowed jersey adornment, along with the number, nickname, logo, school name and player name.
The NFHS Sports Medicine Advisory Committee's lightning guidelines (printed in the football rules book appendix) set the default policy:
The guidelines also call for staff assigned to monitor the weather, an evacuation plan with identified safe areas, and an annual review of the policy with administrators, coaches and game personnel.
Under NFHS rules, any player who shows signs, symptoms or behaviors consistent with a concussion must be immediately removed from the game and can't return until cleared by an appropriate health-care professional.
Signs officials can spot (CDC HEADS UP): appearing dazed or confused, slower answers or reactions, clumsiness or unsteadiness, vomiting soon after the hit, and changes in mood or behavior. Loss of consciousness, seizures, slurred speech or increasing confusion are danger signs that need emergency care.
CDC's message for officials: "When in doubt, get them out." You don't diagnose; you get the player removed and let health-care professionals evaluate. The NFHS Suggested Guidelines for Management of Concussion in Sports appear in the rules book appendix.
Arm sleeves (Rule 1-5-2d), effective with the 2027 season: arm sleeves, attached or unattached, that are manufactured to enhance contact with the ball or an opponent must meet the SFIA specification at the time of manufacture and carry a permanent, visible, legible SFIA seal on the outside.
The rule was adopted in 2025 with a delayed start so manufacturers, players and coaches can prepare. It isn't enforced in 2026.
