The NFL's new overtime rules apply to both the regular season and the playoffs. In the regular season, overtime lasts 10 mins, and if no team wins, it's a tie.
The National Football League has implemented the new overtime rules, previously used for playoff games, for regular-season as well as post-season games. The first overtime of this season took place in the Week 2 match-up between New York Giants and the Dallas Cowboys.

However, unlike the playoffs, in the NFL regular season, there is no double overtime — games can only go into one 10-minute overtime period, and if neither team wins, it ends in a tie.
The new rules around overtime sparked a lot of confusion among fans, as the Dallas vs Giants game saw the first overtime being played. The high-voltage conlusion of the match ended with a disappointment for Jerry Jones' team, as they lost 37-40.
