What is the Boundary Line on the Football Field?
The boundary line in football is made up of the end lines and sidelines, which also define the perimeter of a football field. When a player steps out of bounds to the sideline with the ball, the play is called dead. If a player catches the football and lands out of bounds, the pass is ruled incomplete. If a player fumbles and the ball rolls out of bounds, the ball is returned to the team that fumbled the ball at the spot of the fumble. The boundary lines are in place to restrict play to a specific area and is used as a sideline area for players to rest and coaches and trainers to stand. The out of bounds boundary lines extend all the way around the football field as white turf, like the yard lines and goal lines turf.
