The Indianapolis Colts are in the playoffs, as if anyone doubted they'd get there. So are the Seattle Seahawks, who qualified before even taking the field.

The unbeaten Colts won their 12th straight game and clinched at least a wild-card berth in the NFC by routing the Tennessee Titans 35-3 on Sunday. Indianapolis is the fifth team in league history to start 12-0, and the first since Denver in 1998.

"I think we were able to focus and be businesslike," coach Tony Dungy said. "We came out with a sense of purpose today."

The Seahawks didn't have to come out at all to clinch the NFC West. When Washington beat St. Louis 24-9, Seattle advanced. The Seahawks play at Philadelphia on Monday night.

Moving into commanding positions in their division races were Cincinnati — yes, the Bengals, who haven't had a winning record since 1990 — and the New York Giants.

The Bengals (9-3) moved two games in front of the Steelers in the AFC North with a 38-31 win at Pittsburgh. The Giants built a 17-0 lead and held on against Dallas 17-10, giving them a one-game edge on the Cowboys in the NFC East.

Other first-place teams who won Sunday were Chicago (NFC North), 19-7 against Green Bay; Carolina (NFC South), 24-6 over Atlanta; and New England (AFC East), 16-3 against the New York Jets.

At Indianapolis, the Colts again looked impressive as their quest for an undefeated season continued.Peyton Manning completed 13 of 17 passes for 187 yards and three touchdowns, giving him 25 this season. That extended his NFL record to eight straight seasons with at least 25 touchdown passes.Edgerrin James carried 28 times for 107 yards and one touchdown, becoming the third-fastest player in league history to 9,000 yards. He now has 9,067 yards in 93 games. Eric Dickerson reached the milestone in 82 games and Jim Brown in 88.Marvin Harrison also joined the milestone club by becoming the 12th player in league history to top 12,000 yards receiving. He did that with his first reception, a 36-yarder on the Colts' opening drive, which also ended with Harrison's 10-yard TD reception — extending the NFL record between the duo to 92.Tennessee (3-9) has lost six straight to Indianapolis and gained only 40 yards on the ground."If somebody's going to have a chance to beat this team before the season is over, they're going to have to take advantage of every opportunity presented to them," Titans coach Jeff Fisher said.

At St. Louis, Clinton Portis ran for 136 yards on 27 carries with a pair of touchdowns for the Redskins (6-6). Portis ran in untouched from 47 yards for the game's first score and Santana Moss' 30-yard catch from Mark Brunell set up Portis' second touchdown on a 1-yarder.Washington held the Rams (5-7) to a season-worst 210 total yards. Rookie Ryan Fitzpatrick, who threw for 310 yards in three quarters last week, was 21-for-36 for 163 yards, got sacked three times and was routinely flushed out of the pocket by the Redskins' rush.

Although Jay Feely clanged a 33-yard field-goal attempt off the crossbar with 5:18 left, New York's defense held on. Feely blew three chances to win a game at Seattle by missing field goals the previous week.But the Giants (8-4) had four sacks, forced two fumbles — including one returned for a touchdown by linebacker Antonio Pierce — and intercepted Drew Bledsoe twice.Tiki Barber gained 115 yards on 30 carries against Dallas (7-5).

At Chicago, Charles Tillman returned one interception 95 yards to set up a field goal, and Nathan Vasher carried a fourth-quarter pick 45 yards for a clinching touchdown as the Bears ended Green Bay's domination at Soldier Field.The Bears (9-3) got their first home victory against the Packers (2-10) since 1993 and extended their winning streak to eight — their longest since the 1985 Super Bowl team started 12-0.On a day when their offense relied on four field goals by Robbie Gould, Chicago prevented Brett Favre from throwing a TD pass against them — he'd done so in an NFL-record 26 straight games.

DeShaun Foster scored two touchdowns and became the first Carolina back to go over 100 yards this season while helping the host Panthers (9-3) snap a three-game losing streak against Atlanta (7-5).Carolina has a two-game NFC South lead over the Falcons, and a one-game advantage over Tampa Bay — setting up another huge division showdown next week against the Bucs.Foster had 131 yards on 24 carries, and another 49 yards on three catches.Michael Vick finished 17-of-35 for 171 yards in the air. He was sacked five times, and intercepted twice.

Adam Vinatieri kicked field goals of 21, 34 and 22 yards to set a club record for points with 1,134 — four more than Gino Cappelletti.Corey Dillon scored on a 1-yard run and Kevin Faulk made three big third-down catches for the host Patriots (7-5). Dillon missed the previous two games with a calf injury, and Faulk, his backup, sat out eight straight with a broken foot.The Jets (2-10) managed only 164 yards against a team that allowed at least 400 in seven of its previous eight games.

At Kansas City, a favorable replay ruling helped the Chiefs (8-4), who challenged the spot on a run that appeared to give Denver a first down near midfield on fourth-and-1 with 2:01 left. They ran the clock down to 3 seconds and moved within one game of the Broncos (9-3), who had won four in a row."The runner was clearly short by a couple of feet of the 48-yard-line," referee Bill Leavy said. "He had to reach the 48. Obviously, the first down was given very tightly. Therefore, when I saw the spot on the field, I knew the first down had not been reached."

At San Diego, Drew Brees threw two touchdown passes for the Chargers (8-4), who won their fifth straight to pull within one victory of the AFC West-leading Denver Broncos.The Broncos lost 31-27 at Kansas City, which is tied for second place — as well as the last wild-card spot — with the Chargers. The defending division champion Chargers beat the Chiefs 28-20 on Oct. 30, and the teams will play again in Kansas City on Dec. 24. The Chargers will host Denver in the season finale on Dec. 31.Of course, San Diego must still play at undefeated Indianapolis, on Dec. 18.The Raiders (4-8) lost their fifth straight to the Chargers.

At Detroit, Brad Johnson threw two touchdown passes, Michael Bennett scored twice and the Vikings (7-5) won their fifth straight, all with Johnson starting for injured Daunte Culpepper.Detroit (4-8) has lost five of six, but this was the first loss under Dick Jauron, who became interim coach when Steve Mariucci was fired last Monday.

Ronde Barber intercepted Aaron Brooks three times and Chris Simms hit Joey Galloway for the only touchdown Tampa Bay (8-4) needed at Baton Rouge.Coming off one of his best outings of the season in a victory over the Jets a week earlier, Brooks threw four interceptions, all in Tampa Bay territory. The Saints (3-9) gained 65 yards on the ground.

At Cleveland, David Garrard threw two touchdown passes in the second half and made a crucial scramble for a first down in the final minutes as the Jaguars (9-3) rallied for their fifth straight win.Rookie quarterback Charlie Frye, making his first career start in place of injured Trent Dilfer for the Browns (4-8), threw two touchdown passes in the first half to Braylon Edwards. But Frye was sacked five times after halftime, and Edwards was helped off the field in the fourth period with a right knee injury.

At Miami, Chris Chambers leaped for his 15th reception of the game, a 4-yard TD on fourth down with 6 seconds left for the Dolphins (4-7). Chambers set Miami records for catches and yards receiving with 238 against the stunned Bills (4-8).Lee Evans caught three touchdown passes to put the Bills ahead 21-0 less than 13 minutes in, and they led 23-3 with 12 minutes left. Struggling Miami quarterback Gus Frerotte was forced to the bench with a concussion in the third quarter, and replacement Sage Rosenfels directed fourth-quarter touchdown drives of 70, 49 and 73 yards.

At Baltimore, the Texans (1-11) blew another one when Matt Stover kicked a 38-yard field goal with 6 seconds left.Kris Brown's fifth field goal with 1:08 to go put Houston in position for its second win of the season. But starting at his 13, Baltimore's Kyle Boller completed a 24-yard pass to Todd Heap on third down and then an 11-yarder to rookie Mark Clayton, and got the Ravens (4-8) in field-goal position with a 35-yard pass to Clayton.

At San Francisco, Kurt Warner threw for 354 yards, and Anquan Boldin turned one of his 11 catches for 156 yards into a 54-yard TD by breaking five tackles, and Larry Fitzgerald had eight receptions for 129 yards for Arizona (4-8).No. 1 draft pick Alex Smith was outstanding before halftime and dismal afterward in his third NFL start for the 49ers (2-10). He was 11-of-12 for 138 yards in the first half, but 5-of-12 with three interceptions after halftime.
