How flexible scheduling will work in the 2021 NFL season

The 2021 NFL schedule is different, and flex scheduling will be different, as well.

As we have a 17-game schedule for the first time in NFL history, a lot of things will be different, and flexible scheduling — the league’s practice of moving games late in the season for maximum viewer enjoyment — will be different as well.

Per the NFL, flexible scheduling will be used in Weeks 11-18. Additionally, in Weeks 5-10, flexible scheduling may be used in no more than two weeks. In Weeks 5-17, the schedule lists the games tentatively set for Sunday Night Football on NBC. Only Sunday afternoon games are eligible to be moved to Sunday night, in which case the tentatively scheduled Sunday night game would be moved to an afternoon start time.

Flexible scheduling will not be applied to games airing on Thursday or Monday nights. In Week 15, two of the five matchups designated as TBD will be played on Saturday with the remainder to be played on Sunday. Specific dates and start times for such designated Week 15 matchups will be determined and announced no later than four weeks prior to game day.

For Week 18, two Saturday games and the Sunday night game will be announced no later than six days prior to January 9. The schedule does not list Saturday games or a Sunday night game in Week 18, but games with playoff implications will be moved to those time slots.

Flexible scheduling ensures quality matchups in all Sunday time slots in those weeks and give “surprise” teams a chance to play their way into primetime. In Week 18, two games will be played on Saturday, one at 4:30 PM ET and one at 8:15 PM ET with the remainder to be played on Sunday afternoon at 1:00 PM ET and 4:25 PM ET, and one matchup to be played on Sunday night at 8:20 PM ET.

Specific dates and start times for Week 18 matchups will be determined and announced following the conclusion of Week 17.
