Rule 2 – Section 12 – Article 2 – Goal Lines and Pylons

The goal line at each end of the field of play runs between the sidelines and is part of the vertical plane that separates the end zone from the field of play. The two goal lines are 100 yards apart (normally). The plane of the goal line extends between and includes the pylons, which are out of bounds. The entire goal line is in the end zone. A team’s goal line is that which it is defending.
