ARTICLE 3. A live ball becomes dead and an official shall sound their whistle or declare it dead:
c. When a touchdown, touchback, safety, field goal or successful try occurs; or when a free kick or a scrimmage kick that is untouched by Team B beyond the neutral zone touches the ground in Team B’s end zone (Rules 6-1-7a, and 6-3-9).
Approved Ruling 6-3-9 I. A33 illegally touches a punt and the ball then rolls into Team B’s end zone, where Team B recovers and advances the ball into the field of play. RULING: The ball is dead when it strikes the ground in the end zone. Team B may choose a touchback or take the ball at the spot of Team A’s illegal touching (Rule 4-1-3c).
