114 Fun Facts About Football Rules

How many downs does the offense get to earn a new first down?

The offense gets four downs to gain the required distance; come up short on the last one and the ball is turned over on downs.

How many points is a touchdown worth?

A touchdown is worth 6 points today, but when point values were first set in 1883 it earned fewer than a field goal; it only reached six in 1912.

How many points is a safety worth?

A safety is worth 2 points and is the least common score in the game; the team that gives one up must also kick the ball away to the other side.

How many seconds does the NFL play clock give a team from the end of the previous play?

The NFL play clock gives 40 seconds from the end of the previous play; let it hit zero before the snap and the offense is penalised five yards.

What color flag does an NFL head coach throw to challenge a ruling on the field?

Red is the challenge flag's colour; a coach who loses the challenge is charged a timeout, so a team with none left cannot challenge at all.

How many timeouts does each NFL team get per half?

Each NFL team gets 3 timeouts per half; unused ones do not roll over, which is why teams burn them at the end of the second quarter.

How does a punt returner signal for a fair catch?

A returner signals a fair catch by waving one arm above his head; once he does, the ball is dead when caught and he may not advance it.

What must an NFL receiver get down in bounds for a sideline catch to count?

Both feet must touch in bounds, or another body part such as a knee or an elbow; a hand does not count, so a diving receiver needs more than his fingertips on the turf.

Which foul is called when an NFL offense has fewer than seven players on the line at the snap?

Illegal formation costs five yards. Only the two men on the ends of that line and the backs behind it may catch a pass, so an end covered up by a teammate outside him may no longer catch one.

On an NFL dynamic kickoff, the ball must reach which area between the end zone and the 20-yard line?

The landing zone is where a kick must come down or be touched; one that falls short of it is treated like a kick out of bounds, and the receivers take over well upfield.

How far must an onside kick travel before the kicking team can legally recover it?

An onside kick must travel 10 yards, or be touched by the receiving team, before the kickers may recover it, and even a clean recovery ends the play.

How long is a regular-season NFL overtime period, in minutes?

If it ends still tied, the game is a tie; only the playoffs keep adding periods until someone wins.

What is the ball-length space between the offensive and defensive lines at the snap called?

The neutral zone is only as wide as the ball is long, and only the snapper may reach into it; a defender who crosses it and touches a blocker is flagged at once, so the play never starts.

Which team calls the coin toss before an NFL game?

The visitors call the coin toss, held within three minutes of kickoff; the winner may defer its choice to the second half, the route a team takes when it wants the ball after halftime.

In the NFL, where is the ball placed after defensive pass interference?

NFL defensive pass interference is a spot foul: the ball is placed at the spot of the foul, so a deep-ball flag can move the offense half the field; college enforcement is gentler.

Which penalty is called when an offensive lineman flinches before the snap?

A lineman who flinches before the snap commits a false start, a dead-ball foul whistled immediately; only a back may be in motion, and never toward the line.

How many seconds is the NFL's shorter play clock after timeouts, penalties and turnovers?

The same shorter clock follows the two-minute warning, an extra point and any replay review.

Since 2015, what may an NFL defense do after blocking an extra-point kick?

Return it for two points: before 2015 the ball was dead the moment the defense got hold of it, and the same reform moved the kick back to the 15-yard line.

Why did the NFL move the touchback on kickoffs into the end zone out to the 35 in 2025?

To encourage more returns: a kick that flew into the end zone now gave up 35 yards of field position, while one that bounced in from the field of play still came out only to the 20.

On an NFL dynamic kickoff, when may coverage players move?

Once the ball bounces or is caught: until then the coverage men wait in a line only five yards from the blockers, which removes the old full-speed run-up and its collisions.

Which condition applied to NFL onside kicks in 2024?

In 2024 the kicking team had to be trailing, in the fourth quarter, and had to declare the kick to the officials, which ended the surprise onside kick.

What is the name for a quarterback's throw straight into the turf to stop the clock?

A spike is legal only if the quarterback takes the snap and throws at once; it stops the clock, but it counts as an incomplete pass and so costs his team a down.

Which foul, if a quarterback commits it in his own end zone, gives the defense a safety?

Intentional grounding there scores for the defense because the penalty would be marked off inside the passer's own end zone; offensive holding in that spot ends the same way.

How does an official signal a safety?

Palms together above the head signals the one score that also costs the conceding team the ball, because it must then free-kick to its opponent.

Which NFL foul is a block on an opponent from behind and below the waist?

Clipping costs 15 yards because of the knee injuries it can cause; the one place the NFL allows it is close-line play, the crush around the snap, and even there only above the knee.

An NFL lineman numbered 50 to 79 may line up as a receiver only after doing what?

Reporting as eligible means telling the referee, who announces it to the defense, and the player must do so again before every such play; that is how a tackle can catch a touchdown pass.

Which foul against a punter costs 15 yards and an automatic first down, so the punting team keeps the ball?

Roughing the kicker is the serious version; merely running into him costs five yards and no automatic first down, so the officials have to judge how heavy the contact was.

If defensive pass interference happens in the end zone, where does the NFL place the ball?

At the 1: in the NFL an end-zone flag carries the offense all the way to the doorstep with a first down, whereas college rules cap the same foul at 15 yards.

After the two-minute warning, an offensive foul that stops the clock triggers what extra consequence?

After the warning, an offensive foul that stops a running clock also brings a 10-second runoff; the offense can avoid it by spending a timeout, if it has one.

Under which rules is an untouched runner down when his knee hits the turf?

NCAA only: college rules down a runner whose knee touches the ground, while in the NFL he may get up and keep running unless a defender touched him or he gave himself up.

What has a punt returner committed by dropping a ball that was never under control?

Touching a punt without ever controlling it is a muff, not a fumble; the kicking team may recover a muff but cannot advance it, hence the pile rather than a touchdown.

After the 1978 'Holy Roller', who on offense may advance a fumble after the two-minute warning?

The player who fumbled is the only one on his team who may advance it; if a teammate recovers, the ball comes back to the spot of the fumble, so batting it forward gains nothing.

What normally happens when both teams foul during a single play?

The fouls offset and the down is replayed, unless one is a 15-yard foul and the other a simple 5-yard one, when the bigger penalty is still marked off.

Under college rules since 2021, what happens starting with the third overtime?

Alternating two-point tries now begin in the third overtime; the idea arrived in 2019, for the fifth, after LSU and Texas A&M needed seven overtimes and 146 points to settle a game.

Whose overtime playoff loss at Kansas City, without ever touching the ball, led the NFL to guarantee both teams a possession?

Buffalo Bills fans watched Kansas City win the coin toss and score a touchdown in January 2022; owners changed the playoff rule that spring and extended it to the regular season in 2025.

Which team was denied a pass-interference call in a January 2019 playoff, prompting the NFL to make the foul reviewable?

New Orleans Saints receiver Tommylee Lewis was hit early by a Rams defender with the NFC title at stake; the review rule that followed lasted only the 2019 season before owners let it lapse.

How far are the NFL's hash marks from each sideline?

NFL hash marks sit 70 feet 9 in. from each sideline; college hashes sit 60 feet in, which makes a wide-side college field goal a much sharper angle.

A runner scores a touchdown if the ball in his hand touches which marker at the corner of the end zone?

The pylon marks each front corner of the end zone, so a ball that touches it while in a runner's possession has broken the plane and the score counts.

How wide are NFL goalposts, measured between the uprights?

NFL uprights stand 18 feet 6 inches apart, the same width as the gap between the hash marks, so every kick is taken from between the posts.

In what year did college football narrow its goalposts to match the NFL's width?

College goalposts were narrowed in 1991 from 23 feet 4 inches to the NFL's width, reversing a 1959 widening, after kickers had become near-automatic.

Where did NFL goalposts stand from 1933 until they were moved in 1974?

On the goal line: shifting the posts to the back of the end zone in 1974 added ten yards to every kick at goal, while Canadian football still plants its posts where the NFL's used to be.

Which AFC West kicker made a 57-yard fair catch kick against the Broncos in December 2024?

Cameron Dicker of the Chargers took it as the first half expired, when a miss cost nothing; the play is rare because most fair catches are made far out of range. His was the first good one since 1976.

On an NFL fair catch kick, which of these is true?

No tee is permitted on a fair catch kick: it must be a drop kick or a held place kick, and the defense has to stand back, so it plays like an unrushed kick at goal.

Which part of the ball must reach the front edge of the end zone for a touchdown?

Any part of it will do, so a runner stopped short can still score by stretching the tip of the ball across while he holds it; his helmet or foot crossing counts for nothing.
