Here are the regular season NFL overtime rules:
Unlike in the regular season, playoff games cannot end in a tie, so the overtime rules change slightly in the postseason.
Here are the postseason overtime rules:
There are three main requirements for completing a catch. The player must:
A player does not have to maintain control the ball through contact with the ground if he makes a football move, and movement of the ball does not automatically result in loss of control.
If a player loses control of the ball, it is an incomplete pass if the ball hits the ground before he regains control, or if he regains control out of bounds.
When a review is initiated, Alberto Riveron, NFL Senior Vice President of Officiating, or a senior designated member of the officiating department, examines the play inside Art McNally GameDay Central in New York. An on-field instant replay technician brings the Referee a Microsoft Surface tablet so they can communicate with GameDay Central and the in-stadium replay official, and review the play. Riveron or a senior designated member of the officiating department makes the final decision on each review.
View this infographic for a full rundown of the NFL’s instant replay review process.
Each team has two challenges per game, each of which requires the use of a timeout. If the challenge is ruled in the team’s favor, the team gets its timeout back. A third challenge is allowed if a team wins its first two challenges.
If a team initiates a challenge with no timeouts remaining or when it is not permitted to do so, it is a penalty and loss of 15 yards.
A team may use a challenge to review these situations:
These situations are not reviewable:
A replay review is initiated by a replay official or a member of the officiating department in Art McNally GameDay Central — the NFL’s officiating command center in New York — during these scenarios:
Teams are not charged timeouts during an official review. There is no limit to the number of official reviews. An official review must be initiated before the next play begins.
Some examples of 5-yard penalties include:
Some examples of 10-yard penalties include:
Some examples of 15-yard penalties include:
The play clock is set to 40 seconds immediately after a play ends (unless it follows one of these scenarios). If the ball is not snapped before the play clock expires, it is a delay of game.
The play clock is set to 25 seconds after certain administrative stoppages, including:
The Referee can reset the play clock to 25 seconds by pumping one hand vertically.
When there is a 10-second runoff, the clock starts on the referee’s signal. A 10-second runoff occurs when a team commits any of these acts after the two-minute warning with the clock running:
There is a 10-second runoff if a replay review of a play after the two-minute warning results in the on-field ruling being reversed and the correct ruling would not have stopped the clock.
This runoff only applies to the offense. The defense always has the option to decline the 10-second runoff and have the yardage penalty enforced, but if the yardage penalty is declined, the 10-second runoff is also declined.
A player is automatically disqualified if they are penalized twice in the same game for:
The player will be automatically disqualified regardless of whether the penalty is accepted or declined by the opponent. The fouls do not have to be judged by the official to be flagrant for the automatic disqualification to occur, and any foul that occurs during the pregame warm-up period will carry over into the game. Note: If a game official judges a foul to be flagrant, he/she may disqualify a player based on one occurrence.
Unsportsmanlike conduct is any act contrary to the generally understood principles of sportsmanship. Some examples include:
The penalty for unsportsmanlike conduct is a loss of 15 yards. If the foul is by the defense, it is also an automatic first down.
Learn about the 2020 rules changes – narrated by NFL Pro Football Hall of Famer Cris Carter.
The Competition Committee voted to expand the rule that protects a player in a defenseless position to include a kickoff or punt returner who is attempting to field a kick in the air, but who has not had time to clearly become a runner. If the player can avoid or ward off impending contact, he is no longer defenseless.
Beginning in the 2020 season, if the offense commits a foul after the ball is made ready for play and causes the clock to stop before a snap during the fourth quarter or overtime, the game clock will start on the snap. Previously, if the clock was stopped for a foul before the five-minute mark of the fourth quarter, the clock would start on the referee’s signal.
The Committee has made permanent that reviews of the following types of plays can only be initiated by the replay official, even if a foul on the play negates the ruling:
The Officiating Department will continue to emphasize the Use of Helmet rule, first adopted in 2018.
The officiating standards for the Use of Helmet rule are:
The Committee is in support of issuing warning letters for any Use of the Helmet fouls in the interior line.
It is intentional grounding if a passer, in danger of losing yardage due to defensive pressure, throws a forward pass without a realistic chance of completion. A realistic chance of completion is defined as "a pass that is thrown in the direction of, or lands in, the vicinity of an eligible receiver."
It is not intentional grounding if the passer:
The penalty for intentional grounding:
If the passer’s entire body (airborne or on the ground) and the ball are beyond the line of scrimmage when the ball is released, it is an illegal forward pass.
Other examples of an illegal forward pass include:
These are the penalties for an illegal forward pass:
It is a safety:
A safety is worth two points. The team that gave up the safety will put the ball in play with a free kick (punt, dropkick, or placekick) from its 20-yard line.
It is not a safety if:
