All the Seattle Seahawks needed was another win at home. No big deal -- they already had 14 in a row.

But Carson Palmer's 31-yard touchdown pass to Michael Floyd with 2:13 left gave the Arizona Cardinals a 17-10 victory Sunday and kept alive their hopes for their first playoff appearance since 2009.

It was Seattle's first loss at home since December 2011. The Seahawks had been vying to clinch the NFC West and home-field advantage throughout the NFC playoffs. They still can clinch the top seed if the 49ers lose at home to Atlanta on Monday night, or with a win against the Rams next week in Seattle.

The Cardinals got the best of the Seahawks because of stout defense, not necessarily because they were the hungrier team, Seattle coach Pete Carroll said.

"We 'must win' every week. That's all we understand, and I'm sure they feel the same way," Carroll said.

The loss didn't come without a dispute.

On the Seahawks' possession after Arizona's go-ahead score, Russell Wilson took aim at Doug Baldwin with a deep pass. The ruling on the field was an interception by Karlos Dansby, a call that stood despite a review. Baldwin insisted that the ball hit the ground.

"I don't think anybody in the stadium had a better view of it than me," he said.

Referee Scott Green was asked about the call after the game, saying, "We didn't have indisputable evidence that it hit the ground, and therefore we went with the call as it was made on the field, which was an interception."

Panthers inspired

There is a message stitched inside the collar of every Carolina Panthers jersey. Two powerful words. "Keep Pounding."

They were spoken by late linebacker Sam Mills during his fight with intestinal cancer and served as a reminder to teammates and friends to never give up, no matter how dire the situation. Linebacker Thomas Davis addressed that message before the game.

The Panthers took the words to heart as Cam Newton, after struggling all afternoon, directed them to the winning touchdown with 23 seconds left in a 17-13 victory over the New Orleans Saints. The Panthers can wrap up the NFC South by beating Atlanta in the season finale.

Newton had been limited to 116 yards passing in the game's first 59 minutes. But he got a final chance with 55 seconds left with the Panthers taking over at their 35-yard line, trailing 13-10, with no timeouts, Newton nursing a sore ankle and top receiver Steve Smith sidelined by a knee injury.

"That's about the best words you can put for the type of game we had," Newton said of Mills' message. "You know we just kept fighting, kept pounding, kept getting after it. We really knew we were one drive away. We were one play away."

Wild finish

The Green Bay Packers got down to the Pittsburgh 1-yard line, but the Steelers held on for a 38-31 victory to stay alive in the postseason race at 7-8.

The Steelers took the lead after a fumble set up Le'Veon Bell's 1-yard touchdown run with 1:28 left. Micah Hyde's 70-yard kickoff return to the Steelers' 31 gave the Packers hope. Green Bay got to the 1, but Matt Flynn's pass to Jarrett Boykin sailed incomplete in the end zone to end the game.

The last few seconds were marred by a false start that pushed the Packers back to the 6 and included a 10-second runoff down to 10 seconds remaining. The Packers didn't get the snap off until three seconds were left, and Flynn said it appeared the umpire was holding up the center but started the clock while backing up.

"I don't know what happened, really," Flynn said. "The operation seemed kind of weird right there."

Bright spot

In a season full of lows for Washington, receiver Pierre Garcon broke Hall of Famer Art Monk's franchise record for most catches in a season by getting to 107 with a game to go. Monk had 106 receptions in 1984.

"It's pretty cool, but with the season going on, it's pretty hard to celebrate anything right now," said Garcon, whose Redskins have lost seven consecutive games to fall to 3-12.

Bears' Melton arrested

Chicago Bears defensive tackle Henry Melton was charged with assault and public intoxication after refusing to leave a bar and fighting with employees in a Dallas suburb.

Melton, a former University of Texas standout, is out for the season because of a torn left anterior cruciate ligament.
