As part of the NFL’s “flexible scheduling” plan, the Week 13 Minnesota Vikings-Arizona Cardinals game on Sunday, Dec. 6 will be played at 8:20 p.m. ET on NBC and the New England Patriots-Miami Dolphins game that day will move to 1:00 p.m. ET on CBS, the NFL announced Tuesday.

The NFL will utilize flexible scheduling on Sundays in Weeks 11-17. Flexible scheduling will ensure quality matchups in all NFL Sunday time slots in those weeks and give teams a chance to play their way onto primetime and into the late-afternoon 4:15 p.m. ET time slot on CBS and FOX.

For each of the flexible scheduling weeks with the exception of Week 17, the NFL will announce the start times of games on Sundays no later than 12 days prior to that weekend. To ensure a Sunday night game and doubleheader games with playoff implications in Week 17, the flexible scheduling decision for that Sunday may be made on six days notice.

The flex schedule game time changes for this Sunday (Nov. 29) are Chicago at Minnesota and Arizona at Tennessee on FOX at 4:15 p.m. ET.
