A receiver appears to drag a toe inbounds, a runner’s knee may have touched the ground, and the stadium waits while officials study a screen. Video review can settle those close calls—but it is not a chance to replay every decision until someone finds a better angle. The rules limit which rulings can be checked, who can ask for a review, and what evidence is enough to change the call.
Who can start a review?
In the NFL, a review can begin in two main ways: a coach can challenge an eligible ruling, or the replay official can initiate a review. Some plays receive an automatic review, so no coach needs to throw a challenge flag.
- Coach’s challenge: A head coach throws a red flag before the next play begins to dispute a reviewable ruling.
- Automatic review: Scoring plays and turnovers are reviewed. In the final two minutes of each half and in overtime, the replay official can review eligible plays without a coach’s challenge.
- Replay assistance: Replay officials can help on certain clear, objective matters, within the rules—for example, an administrative detail that can be established from video. This does not turn every judgment call into a review.
Coaches generally cannot challenge during the final two minutes of a half or overtime; those reviews are handled by the replay official. A coach also needs an available timeout to challenge. The NFL gives each team two challenges and awards a third if the team wins both of its first two.
What happens during a coach’s challenge?
- The coach throws the flag. It must happen before the next snap, and the ruling must be one the rules allow a coach to challenge.
- The referee announces the review. The game pauses while the referee and replay officials examine available camera angles.
- The video is checked against the replay standard. The original ruling stands unless the video provides clear and obvious evidence that it was wrong.
- The referee announces the result. The ruling is either confirmed, stands, or is changed. The officials then set the ball, clock, and game situation accordingly.
If the coach wins, the ruling is changed and the team keeps its timeout. If the coach loses, the ruling remains and the team is charged a timeout. A team that has no timeouts cannot challenge.
“Confirmed” and “stands” are related, but not identical. Confirmed means the available video supports the original call. Stands means there is not enough clear evidence to change it, even if the replay does not conclusively prove the call was right. In both cases, the original ruling remains in place.
Which plays can be reviewed?
Replay is mainly for rulings that can be checked against objective evidence: where a player or ball was, who had possession, and when something happened. Common reviewable situations include whether a catch was completed, whether a player stepped out of bounds, whether a runner was down before losing the ball, and whether the ball crossed the goal line or line to gain.
For example, imagine a running back stretches toward the goal line and the ball disappears beneath a pile. If the ruling on the field is a touchdown, replay can examine whether the ball broke the plane before the runner was down or fumbled. If the video clearly shows the ball short of the goal line, the call can be changed. If bodies block every useful angle, the touchdown may stand because the video has not clearly disproved it.
Not every important call is reviewable. In the NFL, most judgment-based penalties—such as holding, pass interference, or roughing the passer—are not subject to ordinary replay challenges. Officials may use video assistance for limited matters, but a replay does not generally let a coach ask whether a defender’s contact “looked like” a foul. The rulebook specifies what can be reviewed, and the referee cannot expand that list during a game.
Why the call on the field matters
The replay standard gives weight to what the officials saw live. Video can offer a better angle, but it can also be misleading: a camera may hide a foot behind a defender, make a close spot look farther downfield, or show the ball moving without revealing when control was lost.
That is why a coach should consider both the likelihood of overturning a call and the value of keeping a timeout. Challenging a close spot early in the first quarter may not be worth it if the video is inconclusive. Challenging a potential turnover late in a close game can be far more consequential—though turnovers receive automatic review in the NFL.
Coaches also need to act quickly. Once the next play begins, the chance to challenge the previous ruling is generally gone. If you are watching at home, that explains why a coach may throw the flag immediately rather than wait for a slow-motion replay on the broadcast.
NFL, college, and high school differences
The basic purpose is similar across levels, but the process is not identical. NFL games use coach challenges and replay-official reviews under league rules. College football commonly uses an on-field replay official who can initiate reviews; the details for coach requests and review procedures can depend on the competition’s rules. High school replay is less universal, and many games do not use it at all.
Some rulings also differ by rulebook. For instance, college football has its own replay procedures for plays such as targeting. If you follow more than one level, avoid assuming that a review rule you saw on Sunday applies unchanged to a college or high school game.

Frequently Asked Questions
Can a coach challenge any call?
No. Only rulings listed as reviewable under that competition’s rules can be challenged. Many penalty judgments, including most holding and pass-interference calls in the NFL, are not reviewable through a standard coach’s challenge.
What happens if the replay is inconclusive?
The original ruling stands. Officials need clear and obvious visual evidence to overturn a call; a close or obstructed angle is not enough.
Can a team challenge after the next snap?
Generally, no. A coach must challenge before the next play begins. There are separate procedures for certain timing or administrative issues, but they are not a way to reopen an ordinary play after the game has moved on.
Does every touchdown get reviewed in the NFL?
Yes. Scoring plays receive an automatic review, so a coach does not need to throw a challenge flag. The review can check relevant details such as possession, whether the player was inbounds, and whether the ball crossed the goal line.
Final Thoughts
Video review is a safeguard for specific, checkable mistakes—not a second set of referees judging every moment from scratch. The call on the field matters, only eligible rulings can be reviewed, and the video must clearly show that the original decision was wrong. Once you know those limits, the pauses, challenge flags, and sometimes frustrating “call stands” announcements make much more sense.
