The Philadelphia Eagles and San Diego Chargers are used to making the playoffs. For the Arizona Cardinals, going to the postseason in consecutive seasons is unfamiliar turf.

The Eagles clinched a postseason berth for the eighth time this decade when they defeated the San Francisco 49ers 27-13 on Sunday. The loss by the 49ers also clinched the NFC West title for the Cardinals after Arizona's 31-24 win in Detroit (2-12). Kurt Warner threw a 5-yard touchdown pass to Anquan Boldin with 1:54 left for the Cardinals.

The Cardinals (9-5) have won consecutive division titles for the first time since 1974-75. Arizona got the news of its division title at 30,000 feet while flying over the greater Chicago area on the way home.

The defending NFC champs are also closing in on another milestone: They haven't won 10 games since 1976.

Donovan McNabb threw for one touchdown and ran for another, DeSean Jackson had 140 yards receiving to lead the Eagles (10-4), who lead the NFC East by a game over the Cowboys. Philadelphia visits the Cowboys for the regular season finale in two weeks. Frank Gore ran for 107 yards, becoming the first player to surpass 100 yards against the Eagles in 24 games, but the 49ers (6-8) couldn't overcome three interceptions thrown by Alex Smith.

The start of the Philly game was pushed back three hours because the city was still recovering from the second-largest snowfall it has seen since records began in 1884. A total of 23.2 inches of snow fell in Philadelphia on Saturday.

The Chargers won their fourth consecutive AFC West title with their 27-24 win over the Bengals combined with Denver's 20-19 loss to the Raiders. Nate Kaeding kicked a 52-yard field goal with 3 seconds left for San Diego after Philip Rivers moved the Chargers 46 yards in 51 seconds with no timeouts to set up the winning kick.

The Minnesota Vikings also clinched the NFC North when the Green Bay Packers lost 37-36 to the Pittsburgh Steelers on the final play of the game. The Vikings lost to the Carolina Panthers 26-7 later Sunday night.

Steelers 37, Packers 36

At Pittsburgh, Ben Roethlisberger ended the game the way he started it by throwing a touchdown pass to Mike Wallace, a desperation 19-yarder on the final play that ended the Packers' five-game winning streak and the Steelers' five-game losing streak.

The Packers (9-5) stalled in their playoff run as they couldn't hold leads of 28-27 and 36-30 in a frantic fourth quarter. Green Bay could have secured a playoff spot with its first win in Pittsburgh since 1970 and a Giants loss or tie on Monday night.
