Two division titles and one wild-card spot are on the line in Week 18's Sunday games.

The NFC South will be decided in the early-afternoon window, while the NFC North and No. 1 overall seed in the NFC will be determined on Sunday night.

The final wild-card spot yet to be clinched comes from the AFC, where the Denver Broncos hold all the power.

Denver must beat the Kansas City Chiefs to qualify for the postseason. A loss eliminates the Broncos because the Cincinnati Bengals defeated the Pittsburgh Steelers on Saturday night.

Cincinnati still needs Denver and the Miami Dolphins to lose to get in, but at least it still has a chance to qualify on the final day of the regular season.

9. Miami (8-8)

The AFC playoff math is incredibly simple to follow on Sunday.

Denver needs to beat Kansas City in the late-afternoon window to clinch the No. 7 seed.

Kansas City is starting Carson Wentz at quarterback and resting a handful of starters, so the final result is already decided by some.

The Broncos still need to go out and win the game, and if they do, they will head to Buffalo on wild-card weekend.

Miami can be the first team to benefit from a Denver loss. The Dolphins need to beat the New York Jets and have Denver lose to clinch the final wild-card spot.

However, winning might be tough for the Dolphins with Tyler Huntley starting at quarterback.

If Denver and Miami both lose, the Bengals will be the No. 7 seed. That would set up an epic quarterback battle between Joe Burrow and Josh Allen next weekend.

Cincinnati's win over Pittsburgh on Saturday allows the Los Angeles Chargers to clinch the No. 5 seed with a victory against the Las Vegas Raiders.

The No. 5 seed is the more ideal spot because that team goes to Houston instead of Baltimore on wild-card weekend.

If the Chargers lose, the Steelers will bounce back up into the No. 5 seed.

NFC Standings

Division Leaders

1. Detroit (14-2)

2. Philadelphia (13-3)

3. Los Angeles Rams (10-6)

4. Tampa Bay (9-7)

Wild-Card Race

5. Minnesota (14-2)

6. Washington (11-5)

7. Green Bay (11-5)

9. Atlanta (8-8)

The Detroit Lions and Minnesota Vikings will do battle in one of the most anticipated regular-season finales in NFL history.

Detroit currently holds the NFC North lead and the No. 1 seed, and if it wins at home, the road to the Super Bowl in the NFC will go through Ford Field.

However, if the Vikings win, they will be the top seed and earn home-field advantage.

The Detroit-Minnesota loser will be the No. 5 seed, and at the moment, earn a trip to face the NFC South champion.

The Tampa Bay Buccaneers just need to beat the New Orleans Saints to clinch the NFC South crown.

A Tampa Bay loss opens the door for the Atlanta Falcons to claim the NFC South with a victory over the Carolina Panthers. Atlanta can't get in as a wild-card team.

Tampa Bay has a chance to overtake the Los Angeles Rams for the No. 3 seed as well. The Bucs can do that with a win over the Saints and a Rams loss to the Seattle Seahawks.

Los Angeles already wrapped up the NFC West title and opted to rest some of its starters in Week 18.

The Nos. 6 and 7 seeds will also be determined on Sunday. The Washington Commanders will be the No. 6 seed with a win over the Dallas Cowboys.

The Green Bay Packers must defeat the Chicago Bears and have Washington lose to Dallas to jump over the Commanders in the standings.
