The officiating positions of back judge and field judge were swapped to become more consistent with college and high school football. The field judge is now 20 yards deep, positioned on the same sideline as the line judge, while the back judge is 25 yards from the line of scrimmage near the center of the field.
Tinted visors on players' facemasks are banned except for medical need.
A defensive player can no longer flinch before the snap in an attempt to draw movement from an offensive linemen.
A team will be penalized immediately for having 12 players in a huddle even if the 12th player goes straight to the sideline as the huddle breaks.
During the season, the rules regarding the coin toss were changed to where the visiting team must make the call before the coin is tossed instead of while it was in the air. On Thanksgiving, the game between the Pittsburgh Steelers and Detroit Lions went to overtime. During the coin toss, Steelers running back Jerome Bettis was heard calling "tails" but referee Phil Luckett claimed he said "heads". The coin landed on tails, and the Lions won the toss and eventually the game on a Jason Hanson field goal. It was later revealed that Bettis had changed his mind during the call and was originally going to call "heads" but stopped. Thus, the rule change was adopted to prevent any further confusion.
