UIL Exceptions to the NCAA Football Rules, in Plain English (2026–27)
Short answer
Texas high school football is played under the NCAA rulebook, as modified by a short annual list of UIL state exceptions. This page walks those exceptions in plain English for 2026–27 — the NCAA rule, what changes in Texas — grouped by theme.
The official list is the 2026 UIL Exceptions to NCAA Football Rules (Eleven Man), revised May 26, 2026, published at taso.org. The biggest practical differences: the clock stops to award first downs, an ejected player may stay in the team area, there is no cap on duplicate jersey numbers, and one-way wearable coach-to-player technology is allowed. UIL also modifies the game’s overall length and halftime — figures this page defers to the official document.
How to read this page (and how to cite these). UIL renumbers its exception items every year to stay in sequence with the NCAA rulebook — the document says so in its own first paragraph. So an item number is a pointer into one year’s PDF, never citable rule text. Cite the underlying NCAA rule number and describe the exception; if you mention an item number, attach the school year, as this page does (“2026–27 UIL Exceptions item 16,” never a bare “#16”).
One more honesty note: this page covers the exceptions in Booth Challenge’s verified rules map — the ones that change how real plays get ruled. It is not a substitute for the official PDF, which is the only complete, authoritative list.
The field & markings
The NCAA book writes stadium requirements for college venues. Texas relaxes some of them for high school fields.
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 1-2-1 | Short yard-line extensions inside the sidelines and at the hash marks are mandatory (1-2-1-b), and a solid white area between the sideline and the coaching line is mandatory (1-2-1-c). | The solid white border and those field markings are recommended but not mandatory. A Texas field without them is not out of compliance. |

Uniforms & equipment
This is the densest cluster of Texas differences, and the one that comes up every August. Start with the most famous line in the whole document — the sock rule:
“Players of a team must wear socks or leg coverings that are identical in color and design…”
NCAA Football Rule 1-4-4-h — the base rule, which Texas then excepts
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 1-4-4-h | A team’s socks or leg coverings must be identical in color and design (with NCAA’s own narrow exceptions for knee braces, injury tape, and barefoot kickers). | Any player may wear white sweat socks in lieu of the team’s matching socks or leg coverings. No paperwork, no limit on how many players. Full explainer here. |
| 1-4-4-a-2 | All helmets on a team must be the same color and design. | One or more players may wear a Guardian Cap, provided it is the same color as teammates’ helmets. A covering may be worn over the cap to make the color match, and logos or numbers are not required on the cap or the cover. |
| 1-4-5 | Jersey design, markings, and logos are tightly specified, with logo placement governed by the institution’s conference. | A jersey may carry words reflecting positive values in place of the player’s name, and a team slogan or acronym — both by local district approval. The UIL logo replaces the NCAA logo. |
| 1-4-5-b | The visiting team wears white; a colored visiting jersey requires the home team’s written agreement plus conference certification of contrast. | A light-colored visiting jersey does not require home-coach agreement, provided the jerseys are obviously contrasting with clearly visible numbers. |
| 1-4-5-c | Numerals must be clearly visible, permanent Arabic numerals of specified sizes, in clear contrast to the jersey color. | Numerals must be clearly visible from press box level and on film. The numeral rule is strictly enforced at the varsity level, and questionable jerseys are certified by TASO. |
| 1-4-6-a-1 | Towels must be solid white, within set sizes, with no words, symbols, letters, or numbers. | Towels may be of school color and may contain the school name, school initials and/or mascot insignia — but still may not contain numbers. |
| 1-4-6-c | Eye shields, eyeglasses, and goggles must be clear and untinted — and the rule says no medical exceptions are allowed. | A player may wear tinted eyeglasses or goggles with a current-season UIL Medical Exemption Form presented to the referee before the game. Tinted eye shields remain prohibited, with no medical exception. |

Jersey numbers
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 9-2-2-e | No more than two squad members may be assigned or wear the same jersey number; violating it is unsportsmanlike conduct charged against the head coach. | There is no limit on duplicate jersey numbers in UIL games. Two restrictions remain: players wearing the same number may not play the same position, and may not participate in the same down wearing identical numbers. |
| 1-4-2-d | A player entering the game with a changed number must report to the referee; the crew informs the opposing head coach and the referee announces the change. Not reporting is an unsportsmanlike conduct foul. | The announcement of a number change depends on whether a referee microphone is in use. The player must still report to the referee, the opposing head coach is still informed, and not reporting the change is still an unsportsmanlike foul. |
2026–27 UIL Exceptions items 14 and 52.
Technology
College football moved fast on technology — up to 18 in-game video tablets on the sideline, and a helmet radio for one player on the field. Texas took a different road on both.
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 1-4-11 | Replay/video equipment is prohibited for coaching during the game, with carve-outs: in-game video tablets (up to 18, usable in the booth, sideline, and locker room) and coach-to-player helmet radio for one player on the field per team. | Technology use is limited to coaching booths and locker rooms — no sideline or team-area use during the game. Game officials do not police restricted sideline use, but they report suspected violations. |
| 1-4-11 | Coach-to-player communication runs through the helmet radio, one player on the field at a time, marked with a green dot. | Coach-to-player communication via one-way wearable technology — watches, wristbands, belt-packs — is permitted, for game calls only, with no limit on how many players wear one. |
| 1-4-11 | Jurisdiction over cameras and communication equipment in the playing enclosure sits with game management, under conference policies. | An audio-free camera may be attached to an official’s cap with the approval of the official, the UIL, and the participating schools. Drone activity outside the limit lines is governed by UIL policy, not conference policy. |
| 1-4-13 | A microphone is mandatory for the referee, used for all game announcements and controlled by the referee. | A Texas exception exists for this rule (2026–27 UIL Exceptions item 27), but this page does not summarize it — check the current UIL document. Worth noticing: the number-change exception above already assumes a referee microphone may or may not be in use in a UIL game. |

Timing & the clock
These are the exceptions most likely to change the outcome of a late-game situation, so they deserve the most care.
First, a caution: the NCAA game is 60 minutes in four 15-minute quarters, and the official UIL document also modifies the game’s overall length and the halftime intermission. Those figures sit outside this page’s verified rules map, so they are deliberately not stated here — get them from the official document. The exceptions below are the ones the map does verify.
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 3-3-2 | The clock-stop for a Team A first down exists only after the Two-Minute Timeout in the 2nd or 4th quarters (3-3-2-e-1); a Team A ball carrier, fumble, or backward pass out of bounds restarts on the snap only after the Two-Minute Timeout (3-3-2-d-2), and on the referee’s signal before it (3-3-2-e-3). | The game clock is stopped to award a first down, and starts on the referee’s signal when Team A is awarded a first down either through play or by penalty. A Team A ball carrier, fumble, or backward pass ruled out of bounds stops the clock, and it restarts on the snap — at any point in the game, not only after the Two-Minute Timeout. |
| 3-2-4-c | Lists the stoppages after which the play clock is set to 25 seconds — including a Team B first down, after a kick down, and after a score. | After a kick down, when the clock is stopped for the listed reasons, the referee signals the play clock set at 25 seconds. On other listed stoppages the play clock is set at 40 seconds and the game clock starts on the snap. |
| 2-29-2 | Each stadium shall have a visual play clock at each end of the playing enclosure, capable of counting down from both 40 and 25 seconds. | Visual play clocks are not mandatory. If available and operated, they must count down from both 40 and 25 seconds. |
| 3-1-1 | Three minutes before the scheduled starting time, the referee shall toss a coin at midfield with the field captains. | The midfield coin toss three minutes before the scheduled start is recommended rather than required. |
| 3-2-1 | The referee declares the half ended after clearing the final play with the crew and instant replay; limited review paths can still follow. | Once the referee declares the half over, no enforcement decision can be changed — there is no reopening the half for an untimed down. |
| 3-3-6 | An injured player must leave for at least one down; the play clock is set at 25 or 40 depending on which team’s player was injured; after the Two-Minute Timeout the opponent may have a 10-second runoff option. | A Texas exception exists for the injury-timeout rule (2026–27 UIL Exceptions item 42). Its exact effect is not summarized here — check the current UIL document before ruling an injury-timeout situation differently in Texas. |

Targeting, ejections & disqualification
Here Texas rewrites what happens after the flag. The NCAA book draws a hard line between a disqualified player and an ejected one:
“An ejected player is one who is declared ineligible for further participation in the game and is not allowed to remain in the team area.”
NCAA Football Rule 2-27-12-b-1
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 2-27-12 | A disqualified player may remain in the team area; an ejected player must leave the playing enclosure under escort and remain out of view of the field for the rest of the game. | In a UIL game, a disqualified or ejected player is not required to leave the team area. The player is still done for the day — under NCAA 10-1-1-b a disqualified or ejected player must leave the game whether the penalty is accepted or declined. What changes in Texas is where a high school kid waits: with his team, not banished from the stadium bowl. |
| 9-1-4 | Targeting is forcible contact to the head or neck area of a defenseless opponent with at least one indicator; the 2026 NCAA penalty is 15 yards plus disqualification, with an experimental tiered structure for repeat fouls across a season. | A Texas exception exists to the combined penalty statement for Rules 9-1-3 and 9-1-4 (2026–27 UIL Exceptions item 49). Its substance is not summarized here — check the current UIL document. And remember the row above: however the disqualification lands, in a UIL game the player may stay in the team area. |
2026–27 UIL Exceptions items 30 and 49.
Kicking
| NCAA rule | What the NCAA book says | What changes in a UIL game |
|---|---|---|
| 6-5-1 | A fair catch kills the ball where caught, and a fair catch of a free kick behind Team B’s 25-yard line gives Team B the ball at its own 25. | A Texas exception exists for the fair-catch rule (2026–27 UIL Exceptions item 45). Its substance is not summarized here — check the current UIL document before ruling a fair-catch play in a UIL game. |

Why nearly every AI tool gets Texas wrong
Ask a general-purpose chatbot a Texas high school rules question and it will usually answer from the wrong book — confidently. Two reasons:
- Texas is an outlier. Nearly every state plays high school football under the NFHS rulebook, so almost all high school rules content on the internet is NFHS content. A tool that does know Texas uses NCAA rules then quotes the plain NCAA text — which, as every table above shows, can be exactly wrong for a Friday night game.
- The exceptions live in an annual PDF. The UIL list is short, renumbered every year, and not written anywhere on the open web in a form a generic search summary will surface and reason about.
The result is a tool that is right about college football and wrong about the game actually being played.
