American Football

At a glance

• The offense receives four downs to gain 10 yards.
• Eleven players from each team are on the field.
• Specialized offensive, defensive, and kicking units rotate by situation.

Player profile. The sport separates highly specialized physical tasks. Linemen produce force in confined contact, backs and receivers accelerate through space, quarterbacks coordinate timing and distribution, defenders diagnose formations and close angles, and kickers repeat precision actions after long periods away from active play.

Where it happens

The field is divided into yard lines between two end zones, making territorial progress visible on every play. Hash marks position the ball, goalposts support kick scoring, and the sideline holds specialized units and substitutions; the ten-yard objective links the geometry directly to the four-down possession structure.

• 100 yd between goal lines plus two 10 yd end zones; 53 1/3 yd wide in the US professional game.

How to play

1. The offense uses runs or passes to gain territory in a series of downs. The defense tackles the ball carrier, covers receivers, and seeks turnovers; special teams handle punts, kickoffs, and place kicks.

The essential rules

1. The offense has four downs to advance at least 10 yards.
2. One forward pass may be thrown from behind the line of scrimmage on a play.
3. A touchdown is scored by possessing the ball in the opponent's end zone.
4. A runner is down under the applicable contact or boundary rule.
5. Players must line up legally before the snap.
6. Blocking and contact are limited by position, timing, and body area.
7. The game clock and play clock govern timing.
8. Possession changes after scores, punts, turnovers, or failed fourth downs.

How the result is decided

A touchdown is worth six points, with an additional kick or play available afterward; field goals and safeties provide other scoring routes. The score reflects both sustained possession and field position, while turnovers or failure to gain the required distance can end a promising drive without points.

How the sport developed

The source presents American football as a development from rugby-like school and college games. The line of scrimmage, downs, legal forward pass, protective equipment, and carefully timed substitutions progressively distinguished it from its relatives and created a stop-start contest built around planned plays.

• Canadian football uses a larger field, 12 players, and three downs.
• Flag football was not yet an Olympic event in this 2020 source.
