The Mark In Gaelic Football
Please note that the ‘Mark’ is now expected to be implemented in Gaelic football. When a player catches the ball cleanly from a kick out without it touching the ground, or another player, on or past the 45m line nearest the kick-out point, he shall be awarded a ‘Mark’ by the Referee.
