Last year, the NFL secured the ability to expand the regular season to 17 games. The league is moving closer to officially implementing a 17-game schedule for 2021.
Via Mark Maske of the Washington Post, expansion of the regular season is “not yet certain,” but it’s currently believed that the league will adjust the annual 20-game slate from 16 regular-season games and four preseason games to 17 and three.
Owners previously had been debating whether to move the preseason to three or to two games. Last year, the NFL had no preseason games, due to the pandemic. This year, the pandemic once again could limit or eliminate the slate of exhibition games.
