GREEN BAY, Wis. (AP) -- The Packers are no longer undefeated.
They coughed up four turnovers yesterday, blowing a second-half lead and handing a 27-20 victory to the Chicago Bears at Lambeau Field.
Bears quarterback Brian Griese threw the go-ahead touchdown to tight end Desmond Clark with just over two minutes left.
Brett Favre took over and drove to the Bears' 31.
But with 13 seconds left, he threw an incomplete pass and then an interception in the end zone to end the game.
In the first half he had marched the Packers up and down the field. But he let Chicago back into the game in the third quarter, when he threw a head-scratching interception to Bears linebacker Brian Urlacher.
The Packers fall to 4-1, while the Bears improve to 2-3.
