The division showdowns were won by the Packers, Panthers and Steelers. On to the playoffs.

Like Seattle, Green Bay finished 12-4 after defeating Detroit 30-20 Sunday. But the Seahawks, who beat St. Louis 20-6, held the tiebreaker because they beat the Packers in the season opener.

“Our main goal coming into the season was winning the division, but getting the No. 1 seed is just as big,” Seattle linebacker K.J. Wright said.

Carolina (7-8-1) became the second division winner in NFL history with a losing record, but has won four in a row after a 34-3 romp at Atlanta to secure the NFC South.

“It feels great,” Carolina running back Jonathan Stewart said. “I mean, it’s a blessing and you just have to cherish these moments right now. … We just believed and played our hearts out and this is where we are.”

Dallas (12-4) already owned the NFC East crown and won at Washington 44- 17.

Pittsburgh (11-5) took down Cincinnati 27-17 to wrap up the AFC North. The Bengals (10-5-1) got a wild card.

Denver’s 47-14 win over Oakland gave the Broncos (12-4) a first-round bye as AFC West champion. New England, also 12-4 by with a victory over Denver, has the top seed, even though it fell at home to Buffalo 17-9.

Indianapolis already had the AFC South title; it beat Tennessee 27-10.

Packers 30, Lions 20

Limping Aaron Rodgers threw two touchdown passes to Randall Cobb, Eddie Lacy gashed Detroit’s defense for 100 yards and the Packers claimed a fourth straight NFC North title.

Bothered by a left calf injury, Rodgers was carted to the locker room after tossing his first score to Cobb late in the second quarter. He hobbled back on to the field in the third quarter with the game tied at 14 and led Green Bay on a drive that ended with a 13-yard score to Cobb.

Steelers 27, Bengals 17

At Pittsburgh, Antonio Brown returned a punt 71 yards for a touchdown and added a clinching 63-yard scoring grab with 2:50 to go. Brown had 212 all-purpose yards.

The victory came at a potentially high cost. Running back Le’Veon Bell left in the third quarter with a hyperextended right knee following a collision with Cincinnati safety Reggie Nelson. Nelson hit Bell low at the end of a 19-yard reception. Steelers coach Mike Tomlin and Nelson had a lively conversation after the game, with Tomlin pointing his finger at the Bengals player several times.

Panthers 34, Falcons 3

At Atlanta, Roman Harper and Tre Boston returned interceptions for touchdowns. A 33-yard fumble return by Thomas Davis set up another touchdown.

In 2010, Seattle was 7-9 and won the NFC West, then beat New Orleans in the wildcard round.

Seahawks 20, Rams 6

At Seattle, Marshawn Lynch scored on a 9-yard run, Bruce Irvin returned an interception 49 yards for a touchdown and the Seahawks capped a six-game win streak. Seattle held five of its final six opponents to less than 10 points.

Ravens 20, Browns 10

At Baltimore, the Ravens kicked a field goal and then took the lead on a 16-yard touchdown pass from Joe Flacco to Torrey Smith with 7:33 left. Flacco’s 2-yard TD throw to Kamar Aiken clinched it.

Chiefs 19, Chargers 7

At Kansas City, Justin Houston had four sacks for the Chiefs (9-7) to break Derrick Thomas’ franchise record with 22 in the season. Cairo Santos kicked four field goals, and Chase Daniel played serviceably in place of injured quarterback Alex Smith.

Cowboys 44, Redskins 17

DeMarco Murray and Dez Bryant broke franchise records. Murray rushed for 100 yards on 20 carries, passing Emmitt Smith for the team single-season mark. Murray’s 1,845 yards bettered Smith’s 1,773 from 1995.

Bryant caught scoring passes of 65 and 23 yards to give him 16 touchdown receptions on the season, breaking Terrell Owens’ team record of 15 set in 2007.

Broncos 47, Raiders 14

At Denver, C.J. Anderson ran for three touchdowns. Peyton Manning helped the Broncos (12-4) to at least a tie for the best record in the NFL for the third consecutive season since his arrival in Denver.

49ers 20, Cardinals 17

Jim Harbaugh got a victory in his final game as 49ers coach. Harbaugh said after the home win against playoffbound Arizona (11-5) on Sunday that he and the 49ers (8-8) are mutually parting ways.

Texans 23, Jaguars 17

At Houston, J.J. Watt had three sacks and a safety and Andre Johnson had 134 yards receiving and a touchdown.

Johnson gave Houston (9- 7) a 21-17 lead with an 8-yard reception early in the fourth quarter. Watt made it 23-17 when he sacked Blake Bortles in the end zone for a safety. The sack gave him 20 1/2 this season, making him the first player in NFL history to have two seasons with 20 or more sacks.

Colts 27, Titans 10

At Nashville, the Colts (11- 5) bounced back from their worst performance this season by nearly matching at halftime what they did offensively in a loss at Dallas. They wound up outgaining the Titans 378-192 as the AFC South champs swept their division a second straight season for the first time in franchise history.

Saints 23, Buccaneers 20

At Tampa, Drew Brees threw a 36-yard touchdown pass to Marques Colston with 1:57 remaining to give the Buccaneers (2-14) the top pick in the draft. New Orleans finished 7-9.

Jets 37, Dolphins 24

Geno Smith had his best game, throwing for a careerhigh 358 yards and three touchdowns in what might be Rex Ryan’s final game as Jets coach.

Eagles 34, Giants 26

Mark Sanchez threw two touchdowns and the Eagles’ special teams scored their seventh TD. Backup tight end Trey Burton returned a blocked punt 27 yards for a score in the third quarter as the Eagles (10-6) snapped a three-game losing streak that knocked them out of playoff contention.

Vikings 13, Bears 9

At Minneapolis, Teddy Bridgewater threw the goahead 44-yard touchdown pass to Adam Thielen in the third quarter. Blair Walsh kicked two field goals, Audie Cole had 11 tackles in his first start of the season, and the Vikings (7-9) ended coach Mike Zimmer’s first year on a winning note.
