Division championships and playoff positioning will be on the line in Week 17.

The Pittsburgh Steelers (10-5) beat the Kansas City Chiefs to clinch a postseason berth and can claim the AFC North title by beating the Cincinnati Bengals in the regular-season finale.

In the NFC North, the Green Bay Packers (11-4) and Detroit Lions (11-4) will settle the championship at Lambeau Field, where Detroit has just one victory in the past 22 years. The Lions held off the Bears on Sunday to reach 11 wins for the first time since 1991 and are 5-0 in the division.

The Atlanta Falcons (6-9) will host the Carolina Panthers (6-8-1) next Sunday, with the NFC South championship and fourth seed in the playoffs on the line. The winner gets a home game in the wild-card playoff round and the loser is eliminated. The Falcons took a 19-17 decision in the first meeting Nov. 16.

Houston, with castoff quarterback Case Keenum re-signed and at the controls, shocked the Baltimore Ravens 25-13. That outcome, coupled with the Chiefs’ loss at Pittsburgh, gives the San Diego Chargers (9-6) new life. A Week 17 win at Kansas City puts San Diego in the playoffs after the same teams battled in the regular-season finale for the No. 6 seed in the AFC last December.
