For the only time in the 2013 NFL season, all 16 games will be played on Sunday. Monday and Thursday night football games are done until next year, with just one primetime contest in Week 17.

To adjust for the NFC and AFC playoff races, the NFL has made some changes to the schedule. Four of the 12 postseason spots are still up for grabs, and none of the NFC divisions have been clinched.

Two contests will serve as unofficial title games for their respective divisions, and they were both moved to later in the day. A returning Aaron Rodgers will lead the Green Bay Packers into Chicago for a matchup with the Bears that will determine the NFC North winner. While that game was changed to the late afternoon, the meeting between the Dallas Cowboys and Philadelphia Eagles was flexed to 8:30 p.m. Eastern time. Without Tony Romo, the Cowboys will look to clinch the NFC East crown on the final "Sunday Night Football" game of 2013.

The New England Patriots will host the Buffalo Bills at 4:25 p.m., since they have a chance at clinching the No.1 seed in the AFC. New England will play at the same time as the Denver Broncos, who currently have home-field advantage throughout the playoffs. The Broncos have a one-game lead over the Patriots, but they would lose the tiebreaker because of their head-to-head matchup.

The New Orleans Saints and Tampa Bay Buccaneers will now play in the late afternoon. The game has put been at the same time as the Arizona Cardinals versus the San Francisco 49ers. A win for the Saints at 1 p.m. would have eliminated the Cardinals from the playoff picture before their game started. Even though New Orleans will battle Arizona for the final NFC wild card spot, they can still take the NFC South with a victory and a Carolina Panthers loss.
