It didn't take Aaron Rodgers long to notice Tim Jennings wasn't playing.
The Packers quarterback went at Jennings' replacement at left cornerback, Kelvin Hayden, and Hayden's replacement at nickel back, D.J. Moore, repeatedly. Neither made a play in coverage.
Hayden allowed six receptions for 76 yards, including James Jones' 29-yard second-quarter touchdown, on which Hayden got knocked off stride on his bump attempt.

Moore gave up six receptions for 119 yards, though he was playing zone on a number of the plays. Moore had a difficult time with Randall Cobb in the slot, and he also gave up an 8-yard touchdown reception to Jones.
The Packers forced the Bears into their nickel personnel with Moore on the field close to 75 percent of the game. Given the opponent, it was the wrong game for Jennings to miss.
Here is what else we learned upon further review.
Grading key: Grades are between 0 and 10 with 0 being complete failure and 10 being perfect.
Both Hayden and Moore missed tackles. Moore should be credited with bringing down running back Alex Green for a loss of 3 and showing good awareness on a blitz to bat down a pass at the line.
Charles Tillman gave up a touchdown to Jones on a perfect throw, but he played a very fine game. He forced a fumble and had a pass breakup that he nearly intercepted.
Jermichael Finley created some matchup problems for the Bears. Conte, the player with the best skill set to challenge Finley, grabbed the tight end's wrist in the end zone and drew a pass-interference penalty that set up a touchdown.
Other than that, both safeties did OK at reading, reacting and tackling.
Lance Briggs promised to play against the Packers like it was his last game. He held true to his word, throwing his body around and making plays sideline to sideline. If every Bear played like Briggs, the Bears would have won.
He was in on 13 tackles, including one that sent Green flying backward a few yards after a 7-yard reception.
Briggs read well, closed quickly and played physically. He took on offensive linemen with pop and came off blocks to make plays. He put a lick on Rodgers to force a throwaway on a blitz and batted down a pass on another blitz.
