Gaelic football (Irish: Peil Ghaelach; short name Peil or Caid), commonly referred to as football or Gaelic, is an Irish team sport. It is a form of football derived from traditional Irish ball games. It is played between two teams of 15 players on a rectangular grass pitch. The objective of the sport is to score by kicking or punching the ball into the other team's goals (3 points) or between two upright posts above the goals and over a crossbar 2.5 metres (8.2 ft) above the ground (1 point).
