- The team fails to get a first down, in four downs they fail to move the ball past a line 10 yards ahead of where they got their last first down. The defensive team takes over the ball at the spot where the 4th-down play ends. A change of possession in this manner is commonly called turnover.
- The offense scores a touchdown or field goal. The team that scored then kicks the ball to the other team in a special play called kickoff.
- The offense punts the ball to the defense. A Punt is a kick in which a player drops the ball and kicks it before it hits the ground. Punts are nearly always made on fourth down, when the offensive team does not want to risk giving up the ball to the other team at its current spot on the field (through a failed attempt to make a first down) and feels it is too far from the other team's goal post to attempt a field goal.
- A defensive player catches a forward pass. This is called an interception and the player who makes the interception can run with the ball until he is tackled, forced out of bounds, or scores.
- An offensive player drops the ball fumbles and a defensive player picks it up. As with interceptions, a player recovering a fumble can run with the ball until tackled, forced out of bounds, or scoring. Passes that are thrown either backwards or parallel with the line of scrimmage (lateral passes) that are not caught do not cause the down to end as incomplete forward passes do; instead the ball is still live as if it had been fumbled. Lost fumbles and interceptions are together known as turnovers.
- While in his own end zone, an offensive ball carrier is tackled, forced out of bounds, loses the ball out of bounds, or the offense commits certain fouls in the end zone. This fairly rare occurrence is called Safety play.

American football is a collision sport. To stop the offense from advancing the ball, the defense must tackle the player with the ball by knocking or pulling him down. As such, defensive players must use some form of physical contact to bring the ball-carrier to the ground, within certain rules and guidelines. Tacklers cannot kick or punch the runner. They also cannot grab the face mask of the runner's helmet or lead into a tackle with their own helmet ("spearing"). Despite these and other rules regarding unnecessary roughness, most other forms of tackling are legal. Blockers and defenders trying to evade them also have wide leeway in trying to force their opponents out of the way. Quarterbacks are regularly hit by defenders coming on full speed from outside the quarterback's field of vision. This is commonly known as a blindside. To compensate for this, players must wear special protective equipment, such as a padded plastic helmets, shoulder pads, hip pads and knee pads. These protective pads were introduced decades ago and have improved ever since to help minimize lasting injury to players. An unintended consequence of all the safety equipment has resulted in increasing levels of violence in the game. Players may now hurl themselves at one another at high speeds without a significant chance of injury. The injuries that do result tend to be severe and often season or career-ending and sometimes fatal.
Brain injuryThe Concussions Committee of the NFL, co-chaired by Dr. Ira Casson, has generally denied that concussions result in permanent brain injury. However, there is some research, reported in 2009, which, using phone interviews based on the National Health survey information, showed increased incidence of diagnosis of memory loss among retired professional football players. Such symptoms are believed related to the effects of such impact and concussion.
Field and players
American football is played on a field 360 by 160 feet (120.0 by 53.3 yards; 109.7 by 48.8 meters). The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Sidelines and end lines are out of bounds. Near each end of the field is a goal line; they are 100 yards (91.4 m) apart. A scoring area called an end zone extends 10 yards (9.1 m) beyond each goal line to each end line. The end zone includes the goal line but not the end line. While the playing field is effectively flat, it is common for a field to be built with a slight crown with the middle of the field higher than the sides to allow water to drain from the field.
Yard lines cross the field every 5 yards (4.6 m), and are numbered every 10 yards from each goal line to the 50-yard line, or midfield (similar to a typical rugby field). Two rows of short lines, known as inbound s lines or hash marks, run at 1-yard (91.4 cm) intervals perpendicular to the sidelines near the middle of the field. All plays start with the ball on or between the hash marks. Because of the arrangement of the lines, the field is occasionally referred to as a gridiron in a reference to the cooking grill with a similar pattern of lines.
At the back of each end zone are two goalposts (also called uprights) connected by a crossbar 10 feet (3.05 m) from the ground. For high skill levels, the posts are 18 feet 6 inches (5.64 m) apart. For lower skill levels, these are widened to 23 feet 4 inches (7.11 m).
Each team has 11 players on the field at a time. Usually there are many more players off the field (an NFL team has a limit of 53 players on their roster, all of which can be dressed for a game). However, teams may substitute for any or all of their players during the breaks between plays. As a result, players have very specialized roles and are divided into three separate units such as the offence, the defense and the special team. It is rare for all team members to participate in a given game, as some roles have little utility beyond that of an injury substitute.

American football is a sports played between two teams of eleven with the objective of scoring points by advancing the ball into the opposing team's end zone. Known in the United States as football, it may also be referred to informally as gridiron. The ball can be advanced by running with it or throwing it to a teammate. Points can be scored by carrying the ball to the opponents goal line, catching a pass thrown over that goal line, kicking the ball through the opponent's goal posts or tackling the opposing ball carrier in his own end zone.
The history of American football can be traced to early versions of rugby football. The game have its origins in varieties of football played in the United Kingdom in the mid-19th century, in which a ball is kicked at a goal, or run over a line. Many games known as "football" were being played at colleges and universities in the United States in the first half of the 19th century.
American football resulted from several major divergences from rugby football, most notably the rule changes instituted by the consideration of the Walter Camp, considered the "Father of American Football". Among these important changes were the introduction of the line of scrimmage and of down and distance rules. In the late 19th and early 20th centuries, game play developments by college coaches which helped take advantage of the newly introduced forward passThe popularity of American Football grew as it became the dominant version of the sport for the first half of the twentieth century. Bowl Games, a college football tradition, attracted a national audience for collegiate teams.
