Thesaurus Term : American Football

Scope note
American football (also known as just football in the United States and gridiron in some other countries) is a sport played by two teams of eleven players on a rectangular field 120 yards (109.73 m) long by 53.33 yards (48.76 m) wide with goalposts at each end. The offense attempts to advance a ball down the field by running with or passing it.

The game is a full-contact sport and minor injuries to players are frequent. Severe injuries often occur because one of the purposes of the game is to injure opponent players to keep them from continuing in the game. The most common types of injuries are strains, sprains, bruises, fractures, dislocations, and concussions. Protective helmets and pads are worn by the players.
