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 passing the ball through the other team's goals (3 points) or a set of two upright posts separated by a crossbar above the ground (1 point).
