The goalposts were originally located on the goal line; this led to many injuries and sometimes interfered with play. The NCAA moved the goal posts to the rear of the end zone in 1927. The NFL (still following NCAA rules at the time) followed suit, but moved the posts back to the goal line starting in the 1932 NFL Playoff Game, a change made necessary by the size of the indoor Chicago Stadium and kept when the NFL rules stopped mirroring the NCAA rules in . The NFL kept the goal posts at the goal line until 1974, when they were moved back to the rear of the end zone, where they have remained since. This was partly a result of the narrowed hashmark distance made in , which had made for easier field-goal angles. The Canadian game still has posts on the goal line.
