NASHVILLE, Tenn. — The Tennessee Titans wanted to head into the playoffs with a little momentum. Thanks to a dominating performance over the Pittsburgh Steelers, they'll have much more than that.

Kerry Collins threw for a touchdown, Chris Johnson and LenDale White ran for a score apiece, and the Titans routed the Steelers, 31-14, yesterday in a showdown of the AFC's best teams. Tennessee clinched the No. 1 seed and home-field advantage throughout the playoffs.

"This was not a statement game by no means," Titans coach Jeff Fisher said. "It was a momentum game. We needed to build momentum for the playoffs and the bye week by playing well and winning the game. The bonus is the second game here at home."

The Titans improved the NFL's best record to 13-2 with their 15th win in 17 games. But they were coming off a loss to Houston in which they failed to score a touchdown for the first time this year and were up against the NFL's stingiest defense.

They snapped back well, ending the Steelers' five-game winning streak and becoming the first team to top 300 yards against Pittsburgh (11-4) this season. They finished with 323 yards.

Pittsburgh coach Mike Tomlin denied his Steelers were flat after a tough stretch in their third road game in four weeks.

"If you don't take care of the football versus good people, it comes back to bite you," Tomlin said.

Tennessee's staunch defense did it without Pro Bowl defensive tackle Albert Haynesworth and end Kyle Vanden Bosch because of injuries. Their replacements helped them rest easy as the Titans sacked Ben Roethlisberger five times and forced him into four turnovers that they turned into 21 points.

Rookie Jason Jones, who started for Haynesworth, had 3 1/2 sacks and forced Roethlisberger into three fumbles. Michael Griffin, a Pro Bowl alternate, came up with two interceptions for Tennessee.

BILLS 30, BRONCOS 23

DENVER — Now it all comes down to a trip to San Diego for the right to represent the woeful AFC West in the playoffs.

The Broncos blew an early 13-0 lead in the second-coldest game in Denver's history, setting up an all-or-nothing matchup against the Chargers next week for the division title.

The Broncos (8-7) led the Chargers (7-8) by three games with three to go, but now face the possibility of having led the West by themselves from opening weekend through Christmas with nothing to show for it.

The Chargers' win at Tampa Bay earlier in the day was blacked out at Invesco Field by Broncos coach Mike Shanahan, who didn't want his team's emotional edge affected by San Diego's fortunes.

Broncos quarterback Jay Cutler threw for 359 yards and broke Jake Plummer's franchise record with 4,210 yards for the season. But Kawika Mitchell's interception at the goal line when the Broncos were threatening for the tying touchdown with less than six minutes left is what Cutler will surely remember most about this game.

The 17-degree temperature at kickoff marked the second-coldest game on record ever played in Denver. The only one colder was the Broncos' game against San Diego on Dec. 10, 1972, when it was 9 degrees.

DOLPHINS 38, CHIEFS 31

KANSAS CITY, Mo. — In the coldest game they ever played, the Dolphins stayed hot.

Chad Pennington threw three touchdown passes, continuing one of the most remarkable comeback seasons in NFL history in temperatures that plunged into single digits. With their fourth victory in a row and eighth in nine games, the Dolphins (10-5) can clinch the AFC East next week just one year after finishing a league-worst 1-15. All they'll have to do is beat the Jets in the Meadowlands.

The temperature at kickoff was 10, with a wind chill of minus-12. Previously, the coldest game the Dolphins ever played was 14 degrees at Foxboro, Mass., on Dec. 11, 1977.

It was the second-coldest game at Arrowhead Stadium, where the Chiefs (2-13) concluded the home portion of what's certain to be the worst season in the 49-year history of the franchise. They were 1-7 at Arrowhead.

A Miami defense that hadn't yielded a touchdown in three weeks gave up four TDs and a season-high 492 yards to the Chiefs. But Pennington, the longtime Jet who was acquired in the offseason, was 26-of-34 in the brutal cold, including two touchdown tosses to Anthony Fasano.

BENGALS 14, BROWNS 0

CLEVELAND — As bad as they've been, the Bengals can brag they're Ohio's best NFL team. And that ain't saying much.

Cedric Benson rushed for a career-high 171 yards on 38 carries and Leon Hall returned one of his three interceptions 50 yards for a touchdown to help the Bengals get their first road win this season, over the hapless Browns on a bone-chilling day.

After losing their first eight games, the Bengals (3-11-1) have won two in a row for the first time since the final two games of 2007. It was their first road win since beating Miami in the finale last season, and the shutout was Cincinnati's first since blanking the Browns, 30-0, on Nov. 26, 2006.

Cleveland (4-11) has lost five straight.

RAIDERS 27, TEXANS 17

OAKLAND, Calif. — In a season with very little to celebrate, Johnnie Lee Higgins gave Raiders fans plenty to cheer about in the home finale. Higgins caught a 29-yard touchdown pass and then returned a punt 80 yards for another score in the third quarter.

It's the first time since the 2002 Super Bowl season the Raiders won their final home game. Still, Oakland (4-11) became the first team in NFL history to lose at least 11 games for six straight seasons.

The Texans (7-8) had won four straight for the first time in team history and were hoping for their first winning season. But Houston could generate little against the lowly Raiders.
