Referee Has Jurisdiction of Each Section.
(a) A Touchdown is made when the ball in possession of a player is declared dead by the referee, any part of it being on, over or behind the opponents' goal line.
(b) The point where the touchdown is marked, however, is not where the ball is carried across the line but where the ball is fairly held or called "down."
NOTE - If the ball is carried across the extension of the side line it is at once dead, and the tokchdown is marked at the point where the side line crosses the goal line.
(c) A Touchback is made when the ball in possession of a player guarding his own goal is declared dead by the referee, any part of it being on, over or behind the goal line, provided the impetus which sent it to or across the line was given by an opponent. The referee shall declare the ball dead when the player in possession of the ball cries "down," or touches it down, or as provided for in Rule 20.
Suggestion. - A touchback is always made when a player touches the ball down in his own goal, the force which put it in goal having come from an opponent.
(d) A Safety is made when the ball in the possession of a player guarding his own goal is declared dead by the referee, any part of it being on, over or behind the goal line, provided the impetus which caused it to pass from outside the goal to or behind the goal line was given by the side defending the goal. Such impetus could come: (i) from a kick, pass, snap-back or fumble by one of the player's own side; (2) from a kick which bounded back from an opponent; (3) in case a player carrying the ball is forced back, provided the ball was not declared dead by the referee before the line was reached or crossed.
A safety is also made when a player of the side in possession of the ball commits a foul which would give the ball to the opponents behind the offender's goal line; also when the ball, kicked by a man behind his goal line, crosses the side line extended behind the goal line.
