The future of the Super Bowl, which kicks off in March, will depend on the quality of the field at the games, according to a source.
The NFL has set a minimum field-goal distance of 40 yards from the end zone, and the rules allow teams to score touchdowns from anywhere on the field.
The rule also allows players to pass the ball to the sideline for a touchdown.
The NFL says it will allow teams a second 10-yard line, a field goal and a touchdown at the other end.
The minimum goal distance for the 2016 Super Bowl was 40 yards.
The league has since increased the field-goals to 50 yards.
The 2016 Super, the last of the three games, will be played in New Orleans on Sunday, Feb. 9.
The next Super will be the 2018 Super Bowl between the Indianapolis Colts and Green Bay Packers.
