GREEN BAY, Wis. -- Aaron Rodgers had a record-setting night for the Green Bay Packers. The Chicago Bears' season is quickly turning into a nightmare.
Rodgers was 18 of 27 for 315 yards, throwing touchdown passes of 73 and 40 yards to Jordy Nelson to help the Packers (6-3) open a 42-0 halftime lead.
Rodgers tied the team touchdown pass record that he shared with Matt Flynn and matched the NFL mark for a half set by Oakland's Daryle Lamonica in 1969.
The 190th meeting of the NFL's oldest rivalry turned into an old-fashioned blowout, and Rodgers watched most of the second half from the sideline in a knit cap.
"We just kind of got things going our way," Rodgers said. "The line did a good job of giving me time to extend plays. If you extend plays, you look down the field and there's Jordy Nelson. He made some nice catches."
A night full of milestones included Rodgers' 16th scoring pass of 70 yards or more to break the record he shared with Denver's Peyton Manning and Rodgers' predecessor in Green Bay, Brett Favre. Rodgers looked just fine two weeks after tweaking his left hamstring in a loss to New Orleans.
The 55 points tied a Packers record at Lambeau Field.
Both teams were coming off byes. The down time didn't help the Bears, who have lost five of six to drop to 3-6.
Their defense has fallen completely apart.
Embattled quarterback Jay Cutler was on his way to having another night to forget at Lambeau Field with two first-half turnovers. He has thrown 12 interceptions in four career games in Titletown.
Cutler was 22 of 37 for 272 yards. His performance surely won't ease the withering criticism the quarterback has faced back home in Chicago.
Rodgers could seemingly do no wrong.
He connected with tight end Andrew Quarless on a 4-yard scoring strike with 3:53 left in the quarter for a 14-0 lead.
But the misery was only just beginning for the Chicago secondary.
Rodgers found Nelson for a 40-yard touchdown pass with 12:17 left in the second quarter. A screen pass to Eddie Lacy on Green Bay's next possession turned into another catch-and-run for a 56-yard score and a five-touchdown lead.
About the only thing that went wrong for the Packers was when Cobb fumbled near the goal line after a 4-yard catch. The Bears recovered in the end zone -- but even that play went awry for Chicago after Kyle Fuller was whistled for unnecessary roughness.
Nelson had six receptions for 152 yards, while Cobb had 72 yards on four catches. He caught a touchdown for the sixth straight game.
Star pass rushers Clay Matthews and Julius Peppers each had sacks. Peppers forced a fumble on his sack against his former team that he recovered at the Chicago 32, setting up another score.
The Packers' league-worst run defense also held Matt Forte to 54 yards on 17 carries. Matthews relished this performance after the defense had an embarrassing second-half letdown in the 44-23 loss to the Saints.
"So much emphasis is put on it," Matthews said about improving defensively. "When we stopped their run and the way our offense was going, it was game over."
The Bears finally snapped the shutout when Cutler connected with Brandon Marshall for a 45-yard touchdown pass with 7:44 left in the third quarter.
Marshall left the game in the fourth quarter with a left ankle injury.
