Favre threw two second-half interceptions to tie George Blanda’s career NFL record of 277, allowing the Chicago Bears to rally for a 27-20 victory at Lambeau Field Sunday night.

But Favre was responsible for only two of the Packers’ five turnovers against a banged-up but ball-hungry Bears team — a surefire recipe for an upstart team to cough up its undefeated record.

“We should have won the ballgame, but we made a lot of mistakes and they capitalized,” Favre said.

Bears at 2-3 and still in the Division Hunt! 

Meanwhile, Bears coach Lovie Smith could say a few words that hadn’t been uttered in Chicago in a while.

We liked our quarterback play,” Smith said.

Playing in his second game in relief of the benched Rex Grossman, Brian Griese did exactly what the Bears (2-3) wanted him to do — nothing flashy, but just enough to win.

“He did a great job managing the game,” Smith said. “Got us out of some tough plays, made good decisions.”

In other words, he was the anti-Rex.

“This was as much as a must-win as you can get for us,” said Griese, who was 15-of-25 for 214 yards with two touchdowns and an interception. “We needed the momentum. We needed the confidence. I thought our guys on both sides of the ball came out and played with heart and character and that’s what I’m most excited about.”

The Packers (4-1) gave away a 10-point halftime lead, and Griese threw the go-ahead touchdown to tight end Desmond Clark with 2:05 left.

Favre came out blazing with 243 yards in the first half and the Packers led 17-7 at halftime despite two first-quarter fumbles by rookie receiver James Jones in Bears territory.
