CHICAGO — Brett Favre's frustration flowed as freely as his tears did a year earlier.

The three-time MVP was at his worst, and now, Green Bay can forget about the No. 1 seed in the NFC.

Brian Urlacher returned an interception for a touchdown for the first time in his career, Adrian Peterson ran for 102 yards, and the Chicago Bears beat the Packers, 35-7, on a frigid Sunday afternoon. The loss wiped out the Packers' shot at home-field advantage throughout the playoffs.

The Packers needed to win this game, beat Detroit next week and have Dallas lose to Washington to capture the No. 1 seed. Instead, it goes to the Cowboys, with Green Bay locked in at No. 2.

"I've been playing 17 years, and that was the worst condition I've ever played in," Favre said. "Excuse? No excuse. It was, but they handled it better than we did. We have historically handled it well. It's kind of our ace in the hole, but today, obviously, it wasn't."

Favre was at his worst on a bone-chilling, windy and at times snowy afternoon, and the Packers (12-3) took their most lopsided loss of the season.

He passed for just 9 yards in the first half and 153 overall, giving him 4,058 this season and putting him over the 4,000-yard mark for the fifth time.

He was 17-for-32 and threw two interceptions. Alex Brown picked him off on the first possession of the third quarter, setting up a touchdown that made it 21-7, and Urlacher ran one back 85 yards early in the fourth after juggling the ball.

"He's had two great, back-to-back games," coach Lovie Smith said of Urlacher, who had two sacks, an interception and a fumble recovery in Monday's loss at Minnesota.

Favre said "it was a tossup" every time he unleashed a pass: "Just when you thought you had it figured out, it would switch around on you."

But Favre, who left Soldier Field in tears after leading the Packers to a win last New Year's Eve, wasn't the only one to have a rough afternoon. The Bears blocked two punts by Jon Ryan, who also dropped a snap and booted a 9-yarder.

The Bears (6-9) had little to celebrate this season, but they got some consolation by knocking off their archrivals twice. And the 35 points were their most against Green Bay since a 61-7 win on Dec. 7, 1980.

Peterson carried 30 times and scored on an 8-yard run in the final minute of the second quarter that gave the Bears a 13-7 lead.

Kyle Orton was steady enough, going 8-for-14 for 101 yards and a 3-yard touchdown pass to Desmond Clark in the third quarter.

Green Bay's Ryan Grant ran for 100 yards, including a 66-yard touchdown run in the second quarter, but with the gametime temperature at 16 degrees and a gusty wind, the Packers never got going.

49ERS 21, BUCCANEERS 19

SAN FRANCISCO — Shaun Hill passed for three touchdowns to lift resurgent San Francisco (5-10), and Michael Clayton landed out of bounds with his catch on a 2-point conversion attempt with 1:20 left for Tampa Bay (9-6).

Nate Clements' 62-yard interception return set up Frank Gore's TD catch with 14:11 left for the 49ers, who beat a team with a winning record for the first time this year. Darrell Jackson and Vernon Davis also caught touchdown passes for San Francisco, which also won consecutive games for the first time since the season's first two weeks.

Jeff Garcia passed for 196 yards and a touchdown against his former team before coach Jon Gruden removed him and most of the Buccaneers' playmakers late in the first half, apparently to rest the NFC South champions.

Luke McCown rallied the Bucs for a late 61-yard TD drive in 85 seconds, with Jerramy Stevens catching his second TD pass. But Clayton's foot was clearly out of bounds when he came down with a pass on the 2-point attempt, and San Francisco recovered the onside kick.

REDSKINS 32, VIKINGS 21

MINNEAPOLIS — Playing the kind of hard-nosed, harder-hitting defense that fallen teammate Sean Taylor was famous for, the Redskins (8-7) shut down Adrian Peterson and set up two early touchdowns with interceptions to take control of their playoff fate with a victory over the sloppy Vikings (8-7).

Todd Collins was 22-for-29 for 254 yards and two touchdowns and Clinton Portis had 124 total yards, threw a TD pass and ran for another score for the Redskins, who can clinch a playoff spot with a win over Dallas next week.

Peterson had nowhere to go all night, gaining just 27 yards on nine carries. Tarvaris Jackson's rebound from a disastrous start came too late for the Vikings, who could have clinched a playoff berth with a win.

Jackson threw two early interceptions as the Vikings fell behind 25-0. He threw a 2-yard TD pass to Jim Kleinsasser in the third quarter and scored on a 6-yard run in the fourth that cut the lead to 25-14.

EAGLES 38, SAINTS 23

NEW ORLEANS — Donovan McNabb passed for 263 yards and three touchdowns, jeopardizing the Saints' chances for making the playoffs.

McNabb no longer showed any effects of his rehabilitation from knee surgery over the summer or an ankle sprain in midseason. His 40-yard scramble on the third play led to a bizarre touchdown after his fumble was recovered in the end zone by Kevin Curtis.

Drew Brees threw for 289 yards and a touchdown, but lost his best receiver when Marques Colston left in the first half with a chest contusion. Still, the Saints (7-8) were in position to tie the game at 21 on the opening drive of the second half when David Patten nearly scored on a first-down pass.

The Eagles (7-8) then stuffed New Orleans on three straight running plays to preserve their one-touchdown lead, taking over possession at their 2. Philadelphia followed with a 15-play, 98-yard, seven-minute scoring drive that McNabb capped with a 9-yard touchdown pass to Greg Lewis.

CARDS 30, FALCONS 27

GLENDALE, Ariz. — Neil Rackers kicked a 29-yard field goal to force overtime, then booted one from 31 yards on the first possession of the extra session to win it for Arizona (7-8).

The Falcons (3-12), who rallied from a 10-point fourth-quarter deficit to take the lead, lost their sixth in a row.

Arizona's Kurt Warner completed 36 of 53 passes for 361 yards and three touchdowns, two to Anquan Boldin, who caught 13 for 162 yards.

Chris Redman, starting for the third straight week, engineered Atlanta's comeback, going 28-for-42 for a career-high 315 yards and two scores.
