A closer look at how the Seahawks' NFC West rivals fared in Week 12 around the NFL:
Arizona Cardinals (9-2)
Arizona won its fifth straight game to maintain its three-game lead in the division over the Seahawks (6-5), netting a 19-13 road win over the division rival San Francisco 49ers.
Cardinals quarterback Carson Palmer ran for the go-ahead 8-yard touchdown with less than three minutes to play and the Arizona defense stopped San Francisco's ensuing drive on fourth down to seal the win ... Palmer finished the day 24-of-40 for 271 yards and has now won 21 of his last 25 starts ... Wideout Larry Fitzgerald had 10 catches for 66 yards and John Brown added five grabs for 99 yards ... Defensive back Tyrann Mathieu led the way with 13 total tackles (one for loss), an interception, and two passes defensed.
Veteran running back Chris Johnson, who suffered a leg/knee injury in Sunday's win, was placed on injured reserve with a designation to return, meaning Johnson must sit out for at least the next eight weeks, putting a potential return at just prior to Super Bowl 50. Fellow running back Andre Ellington hurt his toe against the Niners and has his status in question this week, meaning rookie David Johnson is expected to take over as the starter. Cornerback Jerraud Powers strained his calf against San Francisco, but should be ready to go.
The Cardinals travel to St. Louis in Week 13 for a meeting with the Rams at the Edward Jones Dome.
St. Louis Rams (4-7)
St. Louis lost its fourth game in a row, a 31-7 setback to the Bengals in Cincinnati.
The Rams defense allowed Bengals quarterback Andy Dalton to complete 20-of-27 passes for 233 yards and three touchdowns and gave up 140 yards on the ground while the St. Louis offense couldn't get going behind quarterback Nick Foles, who finished 30-of-46 for 228 yards and three interceptions, one of which was returned 19 yards for a touchdown ... Wide receiver Tavon Austin scored the Rams' only touchdown of the day on a 5-yard run in the second quarter.
Case Keenum, who didn't play against the Bengals because of a concussion he suffered the week prior, should return to the starting quarterback role this week.
The Rams host the Cardinals in Week 13 at St. Louis' Edward Jones Dome.
San Francisco 49ers (3-8)
San Francisco lost its second straight game, falling 19-13 to the division-leading Cardinals at Santa Clara's Levi's Stadium.
The Niners defense gave up a fourth quarter touchdown run to Cardinals quarterback Carson Palmer and San Francisco signal caller Blaine Gabbert couldn't orchestrate a comeback in the game's final two minutes, connecting 18 yards with wide receiver Anquan Boldin on a fourth-and-20 play to end the game ... Gabbert finished the day 25-of-36 for a career-high 318 yards, one touchdown, and one interception ... The Niners offense went 0-of-9 on third down, the first time San Francisco has failed to convert a single third-down try since 2010 ... Boldin led all 49ers pass catchers with eight grabs for 93 yards ... Tight end Vance McDonald had six catches for 71 yards and a touchdown.
Tight end Garrett Celek was carted off the field in the first quarter with a high ankle sprain and did not return.
The 49ers head to Chicago for a Week 13 battle with the Bears at Soldier Field.
