Happy New Year!

CHICAGO (AP) -Brett Favre had his way in what could be his last game. Rex Grossman looked lost, and the Chicago Bears bore little resemblance to a No. 1 playoff seed.

Favre showed he still has some ammo left in that gunslinging right arm, passing for 285 yards to lead the Green Bay Packers to a 26-7 victory on Sunday night.

But he may not use that ammo next season, tearfully hinting he is seriously considering retirement, as he did in the last offseason.

"If this is my last game, I want to remember it," Favre said, his voice cracking and tears streaming from his eyes. "It's tough. I love these guys. I love this game. What a great way to go out against a great football team. I couldn't ask for a better way to get out."

Favre said he would discuss retirement with his family and make his announcement soon - "probably within the next couple of weeks."

The three-time MVP completed 21-of-42 passes with a touchdown and interception in what could be his last game. He had 209 yards in the first half alone as the Packers grabbed a 23-0 lead.

Grossman, simply, was awful.

He was 2-of-12 with three interceptions - two of which were returned for touchdowns - and a zero passer rating in the first half. And the debate over whether he or Brian Griese should start is back on.

Griese started the third quarter and was 5-of-15 for 124 yards with two interceptions. He also threw a 75-yard touchdown pass to Mark Bradley with 34 seconds left in the third. The Bears' best passer may have been punter Brad Maynard, who connected with Adrian Peterson for 37 yards on a fake early in the third quarter.

Favre, by contrast, led the Packers on a 75-yard touchdown drive to start the game, and Nick Collins returned an interception 55 yards late in the first quarter to give the Packers a 13-0 lead. Dave Rayner kicked a 25-yard field goal with 49 seconds left in the first half, and Grossman immediately struck again.

This time, Patrick Dendy returned an interception 30 yards to make it 23-0, and the Packers never looked back.

The Packers were all but eliminated from the postseason when the New York Giants beat Washington on Saturday. And their final hopes were dashed before Sunday's kickoff.

Still, they took it to a Chicago team that has homefield advantage throughout the playoffs and was trying to become just the fourth team to go undefeated in conference play since the AFL and NFL merged in 1970.

Favre immediately served notice that he's going out in style - if this is his last game.

The opening drive ended with a 9-yard strike to Donald Driver.

Favre waited until late April before announcing he would play this year, and he was noncommittal about his future this week. He seemed rejuvenated after enduring his worst season in 2005, when he threw 20 touchdowns and 29 interceptions as the Packers went 4-12. He became the NFL's all-time leader in completions, passing Dan Marino, and entered the game with 3,600 yards and 17 touchdowns to go with 17 interceptions.

Meanwhile, Grossman reverted to his midseason form, when he threw 14 interceptions in seven games.

Nathan Vasher intercepted Favre, but five plays later, Collins picked off a screen intended Desmond Clark and returned it 55 yards to make it 13-0 with 50 seconds left in the first quarter. The Bears' next possession ended when Grossman fumbled away the snap.

The Chicago defense wasn't any better.

It had allowed at least 327 yards in the previous five games - thanks to injuries, general sloppiness and defensive tackle Tank Johnson's suspension after his arrest on weapons charges and then shooting death of his friend at a nightclub less than 48 hours later.

Johnson did not start but entered the game on the opening possession, after being inactive against Tampa Bay on Dec. 17 and serving a one-game suspension the following week against Detroit.

Notes: Green Bay's Ahman Green ran for 71 yards and became the first Packer to rush for at least 1,000 six times. ... Chicago's Cedric Benson rushed for 109 - his first 100-yard game. ... Bears returner Devin Hester left in the third quarter with a leg injury. ... Chicago CB Charles Tillman missed his second straight game because of a sore back, while Packers WR Greg Jennings was out with an ankle injury.
