1986 NFL season

The 1986 NFL season was the 67th regular season of the National Football League. The season ended with Super Bowl XXI when the New York Giants defeated the Denver Broncos to win their first league title in 30 years.

Major rule changes

 * Players are prohibited from wearing apparel, equipment, or other items that carry commercial names, names of organizations, or any type of personal message unless they get specific permission from the league.
 * If the offensive team commits a dead ball foul during the last two minutes of a half, the clock will start at the snap.
 * If an offensive player fumbles the ball and it goes forward and out of bounds, the ball is returned to that team at the spot of the fumble.
 * If an offensive player fumbles the ball in the field of play and it goes out of bounds in the opponent's end zone, the ball is given to the defensive team at the spot of the fumble (this rule would be changed in 1991 to result in a touchback).
 * A limited system of instant replay was adopted to aid officiating. A replay official in a booth would decide what plays to review and make the final ruling, regardless of the current score or the amount of time left in the game. The replay official communicated with the game officials via radio transmitters. However, there was no time limit on how long the replay official could review a play and this led to long game delays (this was a major reason why the system was eventually repealed in 1992 and not brought back until time limits for replays were established).
