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

Also qualifying for the Super Bowl chase were the Ravens, who got the final AFC wild card. And the Seahawks secured home-field advantage in the NFC playoffs, not a pleasant prospect to the rest of the conference.

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.

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.

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.

Detroit has not won in Wisconsin since 1991.

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 wild-card 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.

To reach the playoffs for the sixth time in seven years, Baltimore (10-6) needed to beat the Browns (7-9) and have San Diego lose in Kansas City. Precisely what happened.

The Browns had lost four straight and were starting rookie quarterback Connor Shaw.

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.

The Chiefs’ only touchdown came when wide receiver Dwayne Bowe fumbled inches shy of the goal line early in the second quarter. Tight end Travis Kelce recovered in the end zone, not only giving Kansas City a 10-0 lead but keeping a dubious streak intact: No Chiefs wide receiver caught a TD pass all season, the first time in at least 50 years that has happened.

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.

Manning, who completed 21 of 37 passes for 273 yards, failed to throw a TD pass for the second time in four weeks after throwing one for 51 consecutive games.

49ers 20, Cardinals 17

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

Anquan Boldin caught a 76-yard TD pass and went over 1,000 yards receiving. Frank Gore ran for 144 yards on 25 carries to go over 1,000 yards rushing for the eighth time in 10 NFL seasons with San Francisco.

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.

Bills 17, Patriots 9

Kyle Orton threw for one touchdown, Anthony Dixon ran for another and the Bills (9-7) finished their first winning season in 10 years.

With the top seed in the AFC playoffs already clinched, the Patriots used quarterback Tom Brady for only the first half and held out tight end Rob Gronkowski and five other starters.

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.

Saints 23, Bucs 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 career-high 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. Giants rookie Odell Beckham Jr. had 12 catches for a career-best 185 yards, including a 63-yard fourth-quarter touchdown.

Vikings 13, Bears 9

At Minneapolis, Teddy Bridgewater threw the go-ahead 44-yard touchdown pass to Adam Thielen in the third quarter. Blair Walsh kicked two field goals.
