SANTA CLARA -- The 49ers likely will find out Sunday night when their Week 18 game against the Arizona Cardinals will be held.
The NFL will determine the dates and times for the final regular-season week once all playoff scenarios are known. Two games will be played on Saturday, Jan. 7, and the remainder will be held on Sunday, Jan. 8.
For teams in the AFC, that information might not be known until after the Monday night game between the Buffalo Bills and Cincinnati Bengals because of its impact on the playoff picture.
The league informed teams this week that the Week 18 game schedule featuring NFC teams likely will be determined Sunday night because no NFC teams play Sunday night or Monday. The 49ers play at the Las Vegas Raiders in Week 17 on Sunday afternoon.
The NFL will consider playoff implications in determining the dates and times of next week’s games. The 49ers-Cardinals game, which will be played at Levi's Stadium, could have playoff seeding implications.
The 49ers (11-4) have qualified for the playoffs as NFC West champions, and currently are in the No. 3 spot but remain in strong contention with the Minnesota Vikings (12-3) for the No. 2 seed. The Philadelphia Eagles (13-2) are in the No. 1 slot, but they have yet to clinch the NFC East over the playoff-bound Dallas Cowboys (12-4).
The two games on Saturday, Jan. 7, are scheduled for 1:30 p.m. PT and 5:15 p.m. PT. There will be 13 games scheduled for the 10 a.m. PT and 1:25 p.m. PT time slots on Sunday, Jan. 8, and there also will be a game Sunday night at 5:20 p.m. PT.
