FOOTBALL RULES

This edition of the Official Playing Rules of the National Football League contains all current rules governing the playing of professional football that are in effect for the 2021 NFL season.

Member clubs of the League may amend the rules from time to time, pursuant to the applicable voting procedures of the NFL Constitution and Bylaws.

Any intra-League dispute or call for interpretation in connection with these rules will be decided by the Commissioner of the League, whose ruling will be final.

Because inter-conference games are played throughout the preseason, regular season, and postseason in the NFL, all rules contained in this book apply uniformly to both the American and National Football Conferences.
