American football |
 | | American football, known in the United States as simply football is a competitive team sport related to, derived from, and somewhat similar to, other forms of football, but differing from most of them in significant ways. |
 | | Professional leagues that no longer exist include the World Football League (WFL,1974-75), the United States Football League (USFL,1983-1985), the XFL (XFL,2001), the All American Football Conference (1946-1949), the American Football League (AFL,1960-1969-merged with the NFL in 1970), and the World League of American Football (WLAF,1991-1993-now NFL Europe). |
 | | The team that was trapped in its own end zone, and therefore conceded two points to the other team, kicks the ball from its own 20-yard line. |
