Orchard Park, NY ? From awful to awesome: In a matter of weeks, J.P. Losman has taken the bumble and stumble out of the Buffalo Bills’ offense.

Delivering on the patience his coaches and teammates have provided him all season long, the second-year starter produced his second straight last-minute, game-winning drive in a 27-24 victory over the Jacksonville Jaguars on Sunday.

Showing poise in avoiding the rush, Losman stepped up in the pocket and threaded a perfect pass to Roscoe Parrish, who kept both toes inbounds at the left sideline for a 30-yard catch. Two plays later, Rian Lindell hit a 42-yard field goal as time ran out.

The last-minute dramatics came a week after Losman hit Peerless Price for a 15-yard touchdown with nine seconds left in a 24-21 win at Houston. This was an equally clutch performance, with Lindell’s field goal coming 28 seconds after the Jaguars tied the game when David Garrard hit Matt Jones for a three-yard touchdown pass.

“You have to call it momentum,” said Losman, who finished 21-of-28 for 169 yards passing. “We’re feeling really, really tight.”

The loss hurt all the more considering Jacksonville had an opportunity to catch Denver and Kansas City, both 7-4, in the AFC wild card hunt.

Chargers 21, Raiders 14

San Diego – With LaDainian Tomlinson and the Chargers looking all too human against Oakland, the star running back keyed yet another second-half rally to give the AFC West-leading Chargers (9-2) their fifth straight win.

Tomlinson, in the midst of an MVP-type season, rushed for two touchdowns and threw for another. He has 24 touchdowns this season, needing five in the last five games to break the NFL record of 28 set by Shaun Alexander during his MVP season last year.

Saints 31, Falcons 13

Atlanta – Drew Brees threw a 76-yard touchdown to Devery Henderson on the third play of the game, then lofted a 48-yarder to Terrance Copper on the final play of the first half, leading New Orleans past bumbling Atlanta.

New Orleans bounced back from losing three of four, boosted its playoff hopes and delivered a crushing blow to an NFC West rival. The Saints (7-4) won without rookie star Marques Colston, who didn’t play because of a sprained ankle.

Bengals 30, Browns 0

Cleveland – Cincinnati picked off Cleveland quarterback Charlie Frye four times in its first shutout win since 1989, and Carson Palmer threw three touchdown passes for the Bengals.

Palmer finished 25-of-32 for 275 yards and connected with Chris Henry for two TD passes as the Bengals (6-5) stayed firmly in the AFC playoff race by beating Cleveland for the fifth straight time.

Before piling up yardage during extended garbage time in the fourth quarter, the Browns (3-8) had only 167 yards – 21 rushing – after three quarters. By then, they were down 30-0 and on their way to dropping to 1-5 at home.

Rams 20, 49ers 17

St. Louis – Marc Bulger threw a five-yard touchdown pass to Kevin Curtis with 27 seconds to go, and St. Louis snapped a five-game skid.

Stymied much of the game, Bulger was 9-for-9 for 66 yards during a 12-play, 80-yard drive for the winning score. He finished 23-for-34 for 201 yards with one touchdown and one interception.

Frank Gore had 134 yards on 21 carries for the 49ers, who missed a chance to keep the pressure on first-place Seattle in the NFC West.

Jets 26, Texans 11

East Rutherford, N.J. – Chad Pennington had his finest passing day in weeks, throwing for 286 yards and a touchdown in New York’s victory over Houston.

Pennington, who left briefly in the third quarter after an injury scare, finished 24-of-31. He connected with Laveranues Coles nine times for 111 yards, including a 12-yard touchdown in the third quarter. Jerricho Cotchery had seven catches for 110 yards.

Vikings 31, Cardinals 26

Minneapolis – Brad Johnson threw for 271 yards and three touchdowns.

Chester Taylor added 136 yards rushing and a touchdown for the Vikings (5-6), and the defense forced five turnovers and allowed just 17 yards rushing to snap a four-game losing streak.

Larry Fitzgerald had 11 catches for 172 yards. Boldin made nine receptions for 136 yards for the Cardinals.

Patriots 17, Bears 13

Foxborough, Mass. – After New England turned the ball over three times inside the Chicago 20-yard line, tight end Benjamin Watson hung onto it when Tom Brady’s two-yard pass found him in the end zone. Patriots cornerback Asante Samuel put an abrupt end to the Bears’ comeback hopes with his third interception with 1:46 to play.

Ravens 27, Steelers 0

Baltimore – Any chance the Steelers had of returning to the Super Bowl was seemingly laid to rest by the Baltimore Ravens.

The Ravens sacked Ben Roethlisberger nine times Sunday and coasted to their fifth straight victory, a blowout that left the Steelers with only a mathematical chance of reaching the playoffs.

Titans 24, Giants 21

Nashville, Tenn. – Vince Young and Adam “Pacman” Jones never gave up, leading a stunning Tennessee fourth-quarter comeback.

The Titans cornerback intercepted two passes and had a 23-yard punt return that revived his teammates in the fourth quarter. Then rookie quarterback Young finished off an improbable rally from a 21-point deficit.

Young ran for a touchdown and threw for two more in the final 9:35 and finished with a career-high 249 yards passing. Rob Bironas kicked a 49-yard field goal with six seconds left.

Redskins 17, Panthers 13

Landover, Md. – Chris Cooley’s 66-yard touchdown reception was the difference in Washington’s win over Carolina.

The victory broke a two-game losing streak for the Redskins (4-7) and gave quarterback Jason Campbell his first win in his second NFL start. The team returned to running the ball and stopping the run, but it took the big play to Cooley with 4:26 remaining to beat the Panthers (6-5).

Colts 45, Eagles 21

Indianapolis – Joseph Addai tied a franchise record with four touchdowns.

Addai opened the game by sandwiching a 10-yard score around two 15-yard runs to give Indy a 21-0 lead and added a late four-yard run. The rookie running back finished with 171 yards.

The Colts (10-1) can clinch their fourth straight AFC South title with a win at Tennessee next week.
