As in prior seasons, for Week 18, the final weekend of the season, the scheduling of the Saturday, Sunday afternoon, and the Sunday night games is not assigned. Sunday afternoon games may also be moved between 1:00 p.m. Only Sunday afternoon games (or those listed as TBD) are eligible to be moved to Sunday night or Monday night, in which case the initially scheduled Sunday/Monday night game would be moved to Sunday afternoon. During the Flex Scheduling Windows, the games initially scheduled for Sunday Night Football (on NBC) and Monday Night Football (on ESPN or ABC) are tentatively scheduled and subject to change. This season, 'flexible scheduling' for Sunday Night Football may be used up to twice between Weeks 5-10, and in the NFL's discretion during Weeks 11-17 and for Monday Night Football in the NFL's discretion in Weeks 12-17.
