Sideline Technology in Texas High School Football: Wristbands, Tablets, Headsets, Drones

Texas high school football is played under NCAA rules as modified by an annual list of UIL exceptions, and technology is one of the places the two books genuinely part ways — in both directions. Texas is more permissive than the NCAA on what a player can wear, and more restrictive on what a coach can hold on the sideline. If you learned one book, the other will surprise you. Here is each question, with the rule behind it.

The NCAA baseline: the rules doing the work

Four neighboring rules in the NCAA book cover essentially all game-day technology:

• Rule 1-4-10 (prohibited signal devices) — what players may wear. This is the rule with teeth.
• Rule 1-4-11 (communication and field equipment) — tablets and video, coach-to-player communication, cameras, and drones.
• Rule 1-4-12 (coaches’ phones and headsets) — the one everybody is thinking of when they say “headsets.”
• Rule 1-4-13 (referee microphone) — the equipment on the officials themselves.

The 2026–27 UIL exceptions document modifies Rule 1-4-11 in four separate places — items 23 through 26 — and touches Rule 1-4-13 as well. Take them one at a time.

Wristbands: paper is always legal — electronics are the Texas difference

First, the ordinary kind. A printed play-call wristband — a laminated card in a plastic sleeve — is not an electronic device and does not communicate with anything. It has been standard equipment at every level for decades. Nothing on this page changes that.

The interesting question is electronic wearables, and here the NCAA book is brutal:

“Players may not be equipped with any wearable electronic, mechanical or other signal devices for the purpose of communicating with any source”

NCAA Football Rule 1-4-10 (the exceptions are a medically prescribed hearing aid and a health-and-safety data device)

And the penalty attached to it, in the book’s own words: “PENALTY—Administer as a dead-ball foul. 15 yards at the succeeding spot. Player is ejected.” The NCAA’s one sanctioned coach-to-player channel is the helmet radio, and it is tightly capped:

“Only one (1) player may be on the field per team at a time with radio receiving capability and the player must be identified by an unbranded green dot on the back midline of the helmet”

NCAA Football Rule 1-4-11-b, coach-to-player communication exception

Texas goes its own way. Under 2026–27 UIL Exceptions item 24, written against the coach-to-player communication provision of NCAA Rule 1-4-11-b, coach-to-player communication via one-way wearable technology — watches, wristbands, belt-packs — is permitted in UIL games, for game calls only, and with no limit on how many players wear one. Every player on the field can have a receiver on his wrist.

Read the limits as carefully as the permission:

• One-way. The device carries the call from the coach to the player. It is not a two-way radio.
• Game calls only. The permission is for transmitting game calls, not a general license for wearable electronics.

Tablets: Texas is stricter than the NCAA, not looser

This is the answer that surprises coaches coming from a college staff or from Friday-night broadcasts of other states. The NCAA book, as of the tablet rules in Rule 1-4-11-a, is generous: standard tablets restricted to in-game video are permissive, and “Tablets may be used in the coaches’ booth, sideline, and locker room” — up to a limit the book states as “A team may have up to 18 standard tablets active, and all team personnel may view the tablets.”

Texas cuts the sideline out of that. Under 2026–27 UIL Exceptions item 23, written against the tablet exception in NCAA Rule 1-4-11-a, technology use in a UIL game is limited to coaching booths and locker rooms. There is no sideline or team-area use during the game. The coach in the box can work the video; the coach on the field cannot.

There is also an enforcement wrinkle worth knowing: under the UIL exception, game officials do not enforce the restricted sideline technology use — they report suspected violations. So a tablet on a Texas sideline is not a flag on the field; it is a report up the chain. Do not confuse that with permission. And one NCAA sentence every sideline should memorize regardless: “Team personnel engaging an official with a tablet to show or review video is guilty of an automatic Unsportsmanlike Conduct foul.” Showing the back judge your replay is a 15-yard mistake under the base book — do not test the proposition in a UIL game either.

Headsets: yes, and they are almost impossible to foul with

Coaches’ headsets live in their own rule, and it opens with the friendliest sentence in the equipment chapter:

“Coaches’ phones, headsets and communication devices are not subject to playing rules penalties before or during the game.”

NCAA Football Rule 1-4-12

The NCAA book caps usage at 23 headsets per team — “Each team may use a maximum of 23 headsets within the team area, coaches’ box, or coaches’ booth. Any squad or team staff member may utilize the headsets” — plus two more for technicians. If a headset system fails, that is a conference-policy matter under the NCAA book, not a foul.

None of the UIL technology exceptions discussed on this page is written against Rule 1-4-12, so coach-to-coach headsets in the booth and team area are the one piece of game-day technology where the two books read the same way for practical purposes. As with everything here, confirm against the current-year UIL document before you rely on it.

Cameras on officials: legal, but the approval chain is different in Texas

NCAA Rule 1-4-11-c prohibits media communication equipment on or above the field or the team area, then lists exceptions — pylon cameras, cable cameras, and this one:

“A camera, with no audio component, may be attached to the cap of any official with prior approval of the conference and the participating institutions.”

NCAA Football Rule 1-4-11-c, exception 3

Texas keeps the cap camera but rewires who signs off. Under 2026–27 UIL Exceptions item 25, written against that exception, an audio-free camera may be attached to an official’s cap with the approval of the official, the UIL, and the participating schools. Notice the first name on that list: in Texas the official wearing the cap has a say, which the NCAA sentence does not give him. And in both books the camera must be audio-free — no microphones on officials other than the referee’s game-announcement mic.

Drones: no over the field, and Texas decides the rest

The NCAA rule is short and absolute where it matters:

“Drones are not allowed over the field or the team area when squad members are present within the playing enclosure. Outside the limit lines, game management (or conference policy) govern drone activity.”

NCAA Football Rule 1-4-11-d

The first sentence is the same on a Texas Friday night: no drone over the field or team area while players are inside the playing enclosure. What changes is the second sentence. Under 2026–27 UIL Exceptions item 26, drone activity outside the limit lines is governed by UIL policy rather than conference policy. A booster club or media outlet planning drone footage of a UIL game needs to be looking at UIL’s drone policy — and, as the NCAA text itself notes, all federal, state, local, and campus law still applies.

Quick reference: the Texas answers

If it comes up on Friday night

For coaches. Wire up as many wristband receivers as you like — one-way, game calls only. Keep the tablets upstairs and in the locker room, not in your hand on the sideline. Your headsets are safe. And never walk video toward an official.

For officials. A Texas sideline full of players wearing receiver wristbands is legal — do not reach for the NCAA 1-4-10 penalty. A tablet in the team area is the opposite case: not yours to flag, but it is a reportable violation under the UIL exception. The tidiest explanation for either sideline is to name the split: NCAA Rule 1-4-11 is modified in Texas — wearables in, sideline technology out.

For parents and fans. If you see a Texas quarterback checking his wrist between snaps, nothing illegal is happening — that is the UIL’s one-way play-calling system, and it is one of the cleanest examples of Texas high school football being played by neither the NFHS book nor the plain NCAA book, but by NCAA rules as Texas amends them.
