The Week 13 Denver Broncos-Kansas City Chiefs game on December 1 will be played at 3:25 PM CST on CBS, the NFL announced today.

The NFL uses "flexible scheduling" on Sundays in Weeks 11-17. Flexible scheduling ensures quality matchups in all NFL Sunday time slots in those weeks and gives teams a chance to play their way onto primetime and into the late-afternoon 4:25 PM ET time slot on CBS or FOX.  

For each flexible scheduling week, with the exception of Week 17, the NFL announces 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, flexible scheduling decisions for that Sunday can be made on six days notice.
