Pittsburgh ? The Pittsburgh Steelers made certain there’s nobody unbeaten now in the NFL … except for Ben Roethlisberger.

The Steelers combined their still-flawless new quarterback with a touch of the old — a Jerome Bettis of yesteryear and a defense that was Steel Curtain-tough — to dominate the Philadelphia Eagles, 27-3, Sunday and leave the NFL without an undefeated team.

The Steelers (7-1) ended the Eagles’ seven-game winning streak a week after halting New England’s record 21-game winning streak with an equally impressive 34-20 victory. Pittsburgh is the only team in NFL history to stop unbeaten teams in consecutive weeks after each had won at least six games.

“Nobody ever thought we’d do this,” said Hines Ward, who scored the first two touchdowns. “We’re giving defensive coordinators heck trying to figure out what we’re going to do, with weapons all over the field and a quarterback who just keeps getting better.”

How much better can Big Ben get than this? Roethlisberger is 6-0 as a starter — the first rookie since the 1970 merger to do that since Pittsburgh’s Mike Kruczek filled in for an injured Terry Bradshaw in 1976.

Here’s the difference: Kruczek didn’t throw a TD pass all season on a team that won behind the Steel Curtain; Roethlisberger (11-of-18, 183 yards, two touchdowns) has thrown for 11 touchdowns while playing with the polish and growing confidence of a much more experienced player.

Roethlisberger drove the Steelers to a 21-0 lead on their first three possessions with the help of Bettis’ 149 yards, his 55th career 100-yard game. The 1978 Steelers were the only other team in franchise history to start 7-1, en route to a 14-2 record and a Super Bowl title.

Ward scored on the first two drives, a 16-yard reverse and a 20-yard reception, then playfully mocked the Eagles (7-1) and star receiver Terrell Owens by flapping his arms Owens-like in the end zone each time.

Owens ended with seven catches for 53 yards, and a heavily pressured Donovan McNabb was 15-of-24 for 109 yards and an interception.

“That just wasn’t our offense out there, but it happens,” McNabb said. “We’re not the first team undefeated that lost.”

Patriots 40, Rams 22

Pittsburgh quarterback Ben Roethlisberger (7) outruns Philadelphia cornerback Dexter Wynn for a first down. The Steelers beat the Eagles, 27-3, Sunday in Pittsburgh.

St. Louis — Adam Vinatieri hit a season-best four field goals, then threw his first career touchdown pass on a fake.

Corey Dillon returned after a one-week absence with 112 yards rushing on 25 carries and a touchdown for the Patriots, whose 21-game winning streak ended in a loss to Pittsburgh last week.

The Patriots (7-1) compensated for an injury-ravaged secondary by sacking Marc Bulger five times, forcing a fumble and intercepting a tipped ball.

Chargers 43, Saints 17

San Diego — Drew Brees, the quarterback the front office didn’t want coming into this season, threw four more touchdown passes — three to tight end Antonio Gates. It was San Diego’s highest-scoring game since beating Miami, 45-20, on Dec. 27, 1993. The Chargers (6-3) won for the fifth time in six games.

Brees was 22-of-36 for 257 yards. Last week he threw a career-high five TD passes in a 42-10 victory over Oakland. He hasn’t thrown an interception in three straight games.

Broncos 31, Texans 13

Denver — Rod Smith became Denver’s career leader in receptions and touchdown catches, and Jake Plummer threw for four touchdowns with no interceptions to help the Broncos (6-3) snap a two-game losing streak. In the first quarter, Smith caught his 676th career pass to surpass Shannon Sharpe on the team’s receptions list. Later, Smith caught a 13-yard touchdown for his 56th score receiving, also passing Sharpe.

Seahawks 42, 49ers 27

San Franciso — Darrell Jackson caught two long touchdown passes from Matt Hasselbeck, and Shaun Alexander rushed for 160 yards and two scores.

Jackson had five catches for 114 yards, and Koren Robinson also caught a TD pass for the Seahawks (5-3), who stayed atop the NFC West with their second straight victory following three straight losses.

Bears 28, Giants 21

East Rutherford, N.J. — The Bears forced five turnovers, including three consecutive plays in a 20-point explosion late in the first half.

Rookie Craig Krenzel threw a 35-yard touchdown pass to ignite the rally, and Anthony Thomas scored on runs of four and 41 yards as Chicago (3-5) won its second straight game and handed the Giants (5-3) their second straight embarrassing home loss.

The Giants also have to worry about a pectoral injury to All-Pro defensive end Michael Strahan, who left in the third quarter.

Bills 22, Jets 17

Orchard Park, N.Y. — Playing in the face of a 25-plus mph wind, Willis McGahee sparked Buffalo’s ball-control offense. McGahee finished with a career-high 132 yards and a touchdown, his third 100-yard rushing game in his third career start.

Buffalo (3-5) won its third game in four outings and third straight at home — all with McGahee as a starter. And the weather has played a factor in all three victories, with winds of 25 mph or stronger blowing off Lake Erie.

Redskins 17, Lions 10

Detroit — Clinton Portis beat the Lions with his legs and right arm. Portis ran for 147 yards on 34 carries and threw a tiebreaking touchdown pass. Detroit (4-4) rallied late, but its hopes for a tying drive ended at the Washington 20 as time expired.

Cardinals 24, Dolphins 23

Miami — The Cardinals met their match in ineptitude, benefited from two critical penalties and drove 70 yards in the final two minutes for a touchdown. Larry Fitzgerald caught the winning score on a two-yard pass from Josh McCown with 19 seconds left after a holding penalty against Miami negated a sack and gave the Cardinals first-and-goal.

Bengals 26, Cowboys 3

Cincinnati — Matt Schobel caught a down-the-middle pass from Carson Palmer and ran 76 yards for a touchdown, leading Cincinnati (3-5). Schobel’s catch broke open a game of conservative play-calling. The Bengals (3-5) also got four field goals from Shayne Graham.

Ravens 27, Browns 13

Baltimore — Jamal Lewis scored the decisive TD with 7:03 left following a seven-yard punt, and Ed Reed sealed the victory in the waning seconds with an NFL-record 106-yard interception return. Back from a two-game suspension, Lewis ran for 81 yards on 22 carries.

Raiders 27, Panthers 24

Charlotte, N.C. — Tyrone Wheatley and Amos Zereoue combined to run for three TDs, and Sebastian Janikowski kicked a 19-yard field goal with six seconds to play.
