SEATTLE -- The Arizona Cardinals (10-5) halted the coronation of the NFC's top team and kept their own postseason hopes alive while ending the Seattle Seahawks' home winning streak at 14 games Sunday afternoon. Arizona went into Seattle and knocked off the team with the NFC's best record, 17-10.
Wide receiver Michael Floyd's diving, 31-yard touchdown reception with 2:13 remaining and the ensuing two-point conversion gave the Cardinals a 17-10 lead and held up as the game-winning score.
Seattle had a chance to make of heroic drive of its own. Quarterback Russell Wilson's pass on the first play of the drive was intercepted by Arizona linebacker Karlos Dansby after bouncing off the arm of outstretched Seattle wide receiver Doug Baldwin with 1:56 remaining. A replay review upheld the call on the field.
Arizona quarterback Carson Palmer had to overcome four interceptions, including two in the opposing end zone, to keep the Cardinals in the running for a wild-card spot heading into next Sunday's game against the San Francisco 49ers. Palmer completed 13 of 25 passes for 178 yards and the 31-yard touchdown to Floyd.
Arizona used a solid defensive effort and three Jay Feely field goals to build a 9-3 lead early in the fourth quarter. Feely's third field goal came with 10:39 remaining, at the end of a drive that included two costly penalties on the Seattle defense and an apparent fumble that was neither called on the field nor via replay.
Seattle responded with its most impressive drive of the day, resulting in an 11-yard touchdown pass from Wilson to tight end Zach Miller to tie the score 9-9 with the extra point pending. Steven Hauschka's initial try was blocked, but the Cardinals were flagged for illegal formation before Hauschka delivered the extra point and a 10-9 lead.
Palmer led the Cardinals right back down the field while getting a key defensive holding call on a third down near midfield, then he threw the game-winning touchdown pass on third-and-6. Floyd dove past cornerback Byron Maxwell and made a juggling catch in the end zone for the eventual game-winner.
Arizona's top-ranked run defense held Seattle running back Marshawn Lynch to 71 yards on 18 carries.
Seattle's Wilson lost for the first time at CenturyLink Field after completing just 11 of 27 passes for 108 yards, with one touchdown and the lone interception.
The Seahawks can still clinch the NFC West title before their season finale if San Francisco loses to Atlanta on Monday Night Football.
The Cardinals overcame three Palmer interceptions to go into halftime tied 3-3 after a first half that was dominated by the defense.
Palmer's third interception came with just 42 seconds left in the half, with Seattle linebacker Malcolm Smith returning it to the Arizona 3-yard line. After Seahawks running back Marshawn Lynch was stopped short of the goal line twice, Wilson threw an incomplete pass from the 1-yard line with 20 seconds left in the second quarter.
A false-start penalty moved the ball back five yards before Seattle kicker Steven Hauschka hit the left upright with his 24-yard field-goal attempt - only his second missed field goal in 17 tries this season.
Arizona had more total yards (182-112) and more first downs (7-5) than Seattle in the first half but had only three points to show for it, largely because of Palmer's three interceptions.
The Cardinals appeared to be on their way to striking first on the opening drive of the game, but an interception in the end zone ended that early threat. Palmer connected with Brittan Golden for a 63-yard reception to the Seattle 13-yard line. But three plays later Seahawks safety Kam Chancellor intercepted a Palmer pass in the back of the end zone.
Palmer was also intercepted by Seattle's Richard Sherman two drives later, ending that possession at the Seahawks' 33-yard line. Seattle then marched on a 13-play, 70-yard drive that resulted in a Hauschka 27-yard field goal for a 3-0 lead 2:18 into the second quarter.
Notes: Seahawks QB Russell Wilson had not lost a home game at Wisconsin, North Carolina State or Seattle since October 2010. ... Carolina's last-minute win over New Orleans earlier Sunday meant that the Cardinals' only hope for the postseason is to win its remaining games. ...Cardinals receiver Larry Fitzgerald (concussion) played Sunday after missing most of the practice week with a concussion. ... Palmer's 63-yard pass to Brittan Golden on the Cardinals' opening drive resulted in the second-longest pass play against Seattle's defense this season. Andrew Luck of the Colts hit T.Y. Hilton for a 73-yard touchdown against the Seahawks earlier this season. ... Starting guard J.R. Sweezy (concussion) was among the Seahawks' inactives. Paul McQuistan, who had already started 12 games at guard and tackle this season, returned to the lineup for Sunday's game. ... Sunday marked the seventh time in 15 starts this season that Palmer has thrown at least two interceptions in a game. ... Hauschka's missed field from 24 yards out came on his shortest attempt of the season - and only his second try from inside 40 yards this year.
