NCAA overtime normally gives each team an equal series—but a defensive score can end it early.

The rulebook and competitions covered

This page applies to NCAA tackle football in Divisions I, II and III under the 2025 NCAA Football Rules Book, supplemented by the 2026 NCAA Football Rules Changes approved in March and April 2026 and effective with the 2026 season. The controlling overtime provision is Rule 3, Section 1, Article 3, “Extra Periods.” The published 2026 changes do not amend that article.

This is not an NFL, NFHS high-school, NAIA, Canadian, youth or collegiate flag-football ruling. A competition that appoints another code or publishes a specific tiebreaker must be checked against that document; this page does not assume that every game described informally as “college football” uses the NCAA procedure.

The four numbers that control the format

• 25-yard line: starting point for each possession series in the first and second extra periods, unless a penalty relocates it.
• Second extra period: a touchdown must be followed by a 2-point try, unless the touchdown itself has already determined the winner and the try is canceled.
• Third extra period: full possessions end; each team instead receives one 2-point try per extra period.
• 3-yard line: the NCAA spot for the third-and-later-extra-period 2-point play, unless moved by penalty. The 5-yard try spot belongs to a different rules family.

One toss sets the order, then first choice alternates

After a fourth-quarter tie, the teams retire to their team areas while the officials review the procedure at the 50-yard line. The referee then conducts a midfield toss with no more than four field captains from each team; the visiting captain calls it.

The toss winner cannot defer. That team chooses either offense or defense first, or the end of the field to be used for both series in the first extra period. The toss loser takes the remaining option and receives first choice of the two options in each even-numbered extra period; first choice therefore alternates in later periods without another coin toss. These are choices about order and field end, not a choice to receive a kickoff.

A series starts at the 25 and can earn new first downs

Rule 3-1-3-d defines an extra period as two possession series. In the first two extra periods, each offense snaps at the opponent's 25-yard line, on or between the hash marks, unless penalty enforcement changes the spot. The ball is placed midway between the hashes unless the offense selects another position before the ready-for-play signal. After that signal, relocation requires a charged timeout, except when preceded by a Team A foul or offsetting fouls.

The series is not limited to four plays. Under Rule 3-1-3-e, the offense keeps the ball until it scores or fails to make a first down. It can earn a new series of downs in the ordinary way. There is no game clock for the extra period, but the ball still has to be put in play under the NCAA readiness and play-clock rules.

A change of possession stays live until the ball becomes dead

An interception or defensive recovery does not end the down immediately. The defense may return the ball and score. If the defense gains possession and the down ends without a score, the original offense's series is over; that offense does not get the ball back to continue its drive.

There is a narrower second-change edge case. If the original offense regains the ball during the same down, it may complete that live down and score, but it cannot earn a first down after regaining possession. If the down ends without a score, its series ends. That distinction is why “the turnover ends the play” and “the offense gets another set of downs after recovering” are both incorrect shortcuts.

Equal opportunities have one important exception

Rule 3-1-3-f normally requires an equal number of possession series in each extra period. A field goal by the first offense therefore does not end the game: the second team receives its series and may win with a touchdown, extend the game with a matching field goal, or lose by failing to score.

The rule expressly removes that equal-series requirement if Team B—the defense for that series—scores other than on a try. A defensive touchdown during a first- or second-period possession therefore ends the game immediately, even if that team had not yet taken its offensive series. By contrast, a defensive score during a try does not invoke this exception; the other scheduled series still occurs. If the second offense scores a touchdown that itself creates a winning total, the approved ruling under Rule 3-1-3 cancels the unnecessary try.

The first extra period allows one or two; the second requires two

After a touchdown in the first extra period, the scoring team may use the ordinary NCAA try choices. Beginning with the second extra period, Rule 3-1-3-f requires a 2-point try after a touchdown unless the touchdown has already decided the game.

Calling the kick “illegal” is too broad. The rule says a one-point try attempt in that situation is not illegal, but it cannot produce a point. The practical result is that the offense must run a 2-point play to add to its score. A try also remains a live scoring play for the defense, subject to the special ending rule above.

Each possession series becomes one play from the 3

Beginning with the third extra period, Rule 3-1-3-e replaces the 25-yard possession series with one play for a 2-point try from the 3-yard line, unless a penalty relocates the ball. Each team's attempt is one possession series; the teams do not receive four downs or continue after an ordinary failed attempt.

After both series, the team with the higher total wins. If the results leave the scores level, the choices rotate and another extra period supplies another pair of tries. Older references that place the shootout in the fifth extra period are superseded by the current Rule 3 wording.

Penalties can move the start, and turnovers add special enforcement

Normal NCAA rules apply unless the extra-period article creates an exception. A foul before the series or during an offensive down can therefore relocate the 25-yard start, the line to gain or a try spot, and an accepted penalty can affect whether the offense continues.

After a change of team possession, Rule 3-1-3-g is more restrictive: penalties against either team are generally declined by rule, a score by a team that fouls during the down is canceled, and special rules govern fouls by both teams. Flagrant personal fouls, unsportsmanlike-conduct fouls, dead-ball personal fouls and live-ball fouls treated as dead-ball fouls are exceptions that can be enforced on the succeeding play. The exact foul sequence matters; “all turnover penalties are ignored” is not a safe ruling.

One in each early period, then one for the rest of the game

Regulation timeouts do not carry over. Each team receives one timeout in the first extra period and a fresh one in the second; an unused timeout from either period does not carry forward. Beginning with the third extra period, each team has one timeout for the remainder of the game—not one new timeout in every shootout round. A timeout taken between extra periods is charged to the succeeding period.

Radio and television timeouts are permitted only after the first and second extra periods. If there is no media timeout after the second, Rule 3-1-3-h supplies a two-minute mandatory break. Under the injury rule effective from the 2025 season, a player who presents as injured after officials have spotted the ball for the next play costs the team a timeout; if none is available, the penalty is five yards for delay of game.

Overtime does not create a separate review standard

Where NCAA instant replay is used, Rule 12 still governs reviewable scoring, catch, loose-ball, goal-line and line-to-gain rulings in extra periods. The 2026 Instant Replay Casebook makes replay optional for a member institution rather than automatic at every NCAA game, so a viewer should not assume every overtime contest has a booth review.

For the 2026 season, a head coach has two challenges and earns a third if at least one of the first two succeeds, but a challenge requires an available team timeout. That requirement can matter after the third extra period begins because each team has only one timeout for the remainder of the game.

A touchdown answers a first-period field goal

Situation: under the NCAA rules effective for 2026, Team A opens the first extra period with a field goal. Team B then scores a touchdown on its possession.

Ruling: Team B wins 6–3 in the extra period and no try is played. Team A's field goal guaranteed Team B its series, but Team B's touchdown itself creates the winning total; the approved ruling cancels a try that cannot change the winner.

A pick-six on the opening series

Situation: Team A throws an interception during the first possession series. Team B returns it for a touchdown without fouling.

Ruling: the NCAA game ends on the touchdown. The decisive fact is not merely the turnover: Team B scored other than on a try, so Rule 3-1-3-f removes the usual requirement for equal possession series.

The offense recovers after throwing an interception

Situation: Team B intercepts Team A, fumbles on the return, and Team A recovers before being tackled short of the goal line.

Ruling: Team A's series ends when the ball becomes dead. Rule 3-1-3-e lets Team A score during that continuing down if it reaches the end zone, but Team A cannot receive a first down after regaining possession following the change.

A defensive score on a third-period try

Situation: in the third extra period, Team A's 2-point pass is intercepted and Team B returns it to the opposite goal for 2 points.

Ruling: Team B receives the 2 points, but Team B must still take its scheduled series. The early-ending exception applies when Team B scores other than on the try; this score occurred during a try. Team B's own attempt can decide whether the period ends or another pair is needed.

How to resolve an NCAA overtime situation

1. Confirm scope: NCAA tackle football under the 2025 book plus the 2026 changes, not another football code.
2. Identify the extra period: first or second means a 25-yard series; third or later means one 2-point try from the 3.
3. Identify the current series: first or second series, and which team is Team A or Team B for that series.
4. Track possession until the ball is dead: a turnover remains live, and a second change may permit a score without creating a first down.
5. Apply the try rule: ordinary choice in the first period; a scoring 2-point attempt required from the second.
6. Check penalties and replay: the sequence around a change of possession controls enforcement, and replay exists only where adopted.
7. Compare the series: normally wait for equal opportunities, unless Team B has scored other than on a try or a later touchdown has already determined the winner.

Five shortcuts that change the ruling

• “Every overtime begins at the 25.” Only the first two do; the third and later are single try plays.
• “NCAA 2-point tries are from the 5.” Rule 3-1-3 uses the 3-yard line for the third-period-and-later play unless a penalty moves it.
• “Both teams always get the ball.” Usually, but a Team B score other than on a try ends the equal-series requirement.
• “A one-point try in the second overtime is a foul.” It is not illegal, but it cannot score.
• “Each shootout round restores a timeout.” From the third extra period, each team has one timeout for the entire remainder of the game.

Do not import NFL or high-school overtime rules

NCAA extra periods have no kickoff or game clock and use the fixed series described above. NFL, NFHS, collegiate flag and other football codes use different starting procedures, timing, possession guarantees and try spots. See the NFL overtime rules for that separate rules family; do not use its field markings to answer an NCAA play.

Which recent change affects overtime now

• 2025 season: the NCAA Playing Rules Oversight Panel limited each team to one timeout for the rest of the game beginning with the third extra period.
• 2026 season: the NCAA's approved 2026 change notice does not amend Rule 3-1-3. The 2025 base-book overtime procedure, including the 3-yard try spot, remains controlling for 2026.
