NFL Challenge and Replay Rules: How Many Challenges Does Each Team Get?
Each NFL team gets two coach's challenges per game, and can earn a third if either of the first two is successful. A lost challenge costs a timeout, and a team with no timeouts left cannot challenge at all. But challenges are only one piece of the NFL's replay system — automatic booth reviews and a quieter tool called replay assist handle far more plays than challenges ever do.
That distinction is where most explanations of NFL replay fall apart. A coach's red flag is the part fans see, but it's the smallest of the three review systems the league actually uses. Here's how all three work together, what can and can't be reviewed, and what changed heading into 2026.
Challenge Rules at a Glance
| Question | Answer |
|---|---|
| Challenges per team, per game | 2, with a chance at a 3rd |
| How to earn the 3rd challenge | Win either of your first two challenges |
| Cost of a lost challenge | One timeout |
| Can you challenge with zero timeouts? | No |
| Who can throw the flag | The head coach, or one designated assistant coach |
| Standard for overturning a call | Clear and obvious visual evidence |
| Who makes the final ruling | NFL officiating department, Art McNally GameDay Central, New York |
| Automatically reviewed (no challenge needed) | Scoring plays, turnovers, final 2 minutes of each half, all overtime plays |
| Penalty for challenging a non-reviewable play | Loss of a timeout (and the play stands) |
How a Coach's Challenge Works
A challenge starts the way it always has: a coach throws a red beanbag onto the field before the next snap, signaling that they want a ruling reviewed. Since a 2025 rule change, the head coach no longer has to throw it personally — he can designate one assistant coach to do it instead.
Every team starts a game with two challenges. Win one, and you lose nothing — no timeout spent, call corrected. Lose one, and you're charged a timeout as the cost of being wrong. Since you need a timeout in hand to challenge in the first place, running out of timeouts also means running out of challenges.
The third challenge is the detail most fans get wrong, and it's actually gotten easier to earn. Under the old rule, a team needed to win both of its first two challenges to unlock a third attempt. Owners changed that in March 2024, adopting a proposal from the Detroit Lions: now a team only needs to win either of its first two challenges to earn the third. There's a hard ceiling, though — no team can ever get a fourth challenge in a game, no matter how many it wins.
Plays That Are Reviewed Automatically
Not every review starts with a coach's flag. The NFL automatically sends certain plays to replay whether a coach wants it reviewed or not, and these reviews don't touch a team's timeouts or challenge count. The automatic-review list covers:
- All scoring plays (touchdowns, extra points, two-point conversions, safeties)
- All turnovers (interceptions, fumbles recovered by the defense, muffed kicks)
- Any play inside the final two minutes of the first half or the second half
- Every play during overtime
- Player disqualifications
In the final two minutes of a half and throughout overtime, coaches lose the ability to challenge entirely — every reviewable ruling in that window is booth-initiated instead. That's a deliberate design choice: the league didn't want a team out of timeouts to be unable to get an obviously blown call fixed in the moment that matters most. (For more on why that two-minute mark carries so many special rules, see our guide to when the NFL clock stops, runs, and resets.)
What Replay Assist Is (and What It Can't Do)
Replay assist is the part of the system most fans have never heard of, because it's designed to be invisible. Instead of stopping the game for a full review, the New York command center can quietly relay a fix to on-field officials between plays when video evidence is obvious — no hooded referee, no stoppage.
Replay assist expanded significantly starting with the 2025 season. Before then, it mostly handled administrative fixes — down and distance, spot corrections. Since 2025, it also steps in on five specific penalty types when the on-field call doesn't match what the video shows:
- Facemask
- Horse-collar tackle
- Hits on a defenseless player
- Roughing the kicker
- Tripping
Here's the part that matters most: replay assist can only correct or downgrade a penalty that was already called on the field — it cannot create a foul that no official flagged. NFL executive vice president of football operations Troy Vincent was explicit about this limit when the change was approved, calling the idea of replay throwing a flag that never existed on the field a "non-starter." For 2026, the league added one narrow exception to that firewall — covered below.
What Can and Can't Be Challenged
This is the table worth bookmarking. The NFL splits rulings into things a coach can throw a flag on and things that are permanently off-limits, no matter how blatant the mistake looks on the broadcast.
| Reviewable (challengeable or auto-reviewed) | Not Reviewable |
|---|---|
| Scoring plays and the ruling on the field | Judgment calls: holding, illegal contact severity, most personal fouls |
| Possession and recovery of a loose ball | Pass interference (called or not called) — see below |
| Whether a runner/receiver was in or out of bounds | Roughing the passer, unnecessary roughness (judgment aspect) |
| Whether a pass was complete, incomplete, or a fumble | The forward progress spot |
| Line-to-gain and first-down measurements | Whether a whistle should have blown early |
| Goal-line and end-zone rulings | Fair catch signal interpretation |
| Number of players on the field at the snap | Field-level discretionary calls like illegal formation, false start timing |
| Correct down and proper penalty enforcement | Any penalty not called on the field (with the narrow 2025-26 replay-assist exceptions above) |
| Whether a kick was good or missed | Sideline warnings, delay-of-game discretion |
The general rule of thumb: factual, visual determinations are reviewable; judgment calls are not. Whether a receiver's toes touched the sideline is a fact a camera can settle. Whether contact on a receiver constitutes defensive holding versus incidental contact is a judgment call the league has decided replay shouldn't referee.
For more on where that line gets drawn on specific calls, see our breakdowns of what counts as pass interference in the NFL and what does and doesn't count as roughing the passer.
Why Pass Interference Isn't Challengeable Anymore
This is the best story in the entire replay rulebook, and it explains why judgment calls stay off-limits to this day.
In the 2019 NFC Championship Game, Rams defender Nickell Robey-Coleman hit Saints receiver Tommylee Lewis well before the ball arrived — a textbook pass interference that no official flagged. The Saints settled for a field goal instead of likely running out the clock, the Rams tied it, and Los Angeles won in overtime en route to the Super Bowl. The non-call was so blatant it became a national story within hours.
The league's response was a one-year experiment for 2019: pass interference calls, and non-calls, became reviewable. It did not go well. Coaches and officials combined for 81 pass interference challenges league-wide, and only 13 succeeded. Replay officials in New York struggled to apply a consistent standard to something that had always been left to a field official's real-time judgment.
By May 2020, Competition Committee chairman Rich McKay said the rule had "received little support" and no team proposed renewing it — it was allowed to expire quietly. Former NFL vice president of officiating Al Riveron later said the experiment had "failed miserably." Pass interference has been off the reviewable list ever since, and it's the league's clearest cautionary tale about forcing a subjective judgment call through an objective review process.
Who Actually Makes the Call
Here's a detail a lot of fans get wrong: the referee standing under the hooded monitor on the field is not the one making the final decision. Since 2017, that authority belongs to the NFL officiating department at Art McNally GameDay Central in New York, which watches every game simultaneously and communicates the ruling to the on-field referee through his headset.
The referee still announces the decision to the stadium and the broadcast, and in some cases is consulted, but the final call — overturn or confirm — is made by the league office in New York. The standard used is "clear and obvious visual evidence": a ruling on the field stands unless the video clearly and obviously shows it was wrong. Ties, in other words, go to the call that was originally made.
Reviews are also meant to move fast. The league has pushed replay officials and the command center to keep most reviews under two minutes, and shifting the final call to a centralized command center in 2017 was explicitly intended to speed up and standardize decisions that used to vary by which referee happened to be under the hood that week.
What's New for 2026
Two changes take effect for the 2026 season, both expanding what happens away from the coach's red flag.
Replay can now eject players without a flag on the field. The replay command center gained the authority to disqualify a player for a flagrant football act or a non-football act (a punch, a stomp, that kind of thing) even when no official threw a flag on the play in real time. This is narrower than a general "replay assist can add penalties" rule — it's specifically about ejections for egregious conduct, not about adding yardage penalties to a play that wasn't flagged.
A one-year replacement-official safety net. Anticipating the possibility of a work stoppage involving the officials' union during the 2026 season, owners approved a temporary provision letting the NFL officiating department correct "clear and obvious misses" made by replacement officials. The rule includes language that ends it automatically once a new contract with the officials' union is reached, so it's built to disappear rather than become permanent.
Beyond those two additions, the base challenge structure — two challenges, a possible third, the timeout cost — is unchanged for 2026.
FAQ
How many challenges does each NFL team get? Two per game, with a chance to earn a third by winning either of the first two.
Do you lose a timeout if you win a challenge? No. Timeouts are only lost when a challenge fails. Winning a challenge costs nothing.
Can you challenge without a timeout? No. A team needs at least one timeout remaining to throw a challenge flag. No timeouts means no challenges, even if the team hasn't used up its challenge count.
Can you challenge pass interference? No. Pass interference was reviewable for one experimental season in 2019, but the rule was scrapped in 2020 after producing inconsistent results, and judgment calls like PI have stayed off the reviewable list since.
Who has the final say on a replay review? The NFL officiating department at Art McNally GameDay Central in New York, not the on-field referee, has made the final call on every replay review since 2017.
What is replay assist, and how is it different from a challenge? Replay assist is a quiet, no-stoppage fix the New York command center can relay to on-field officials for clear and obvious errors — including, since 2025, five specific penalty types (facemask, horse-collar, hits on a defenseless player, roughing the kicker, and tripping) when the video shows the contact didn't meet the standard the officials called. Unlike a challenge, it doesn't require a coach's flag and doesn't cost a timeout — but it can only correct a penalty that was already called, not invent one from scratch.
What happens if you challenge a play that isn't reviewable? The challenge is denied outright and the team loses a timeout, even though no review actually took place.
