What it means: The Packers are in serious trouble if the left-shoulder injury quarterback Aaron Rodgers sustained in the first quarter is serious. If it turns out to be something like a broken collarbone, Rodgers almost certainly would miss multiple weeks. Rodgers landed hard on his left shoulder after he was sacked by Bears defensive end Shea McClellin on the game's opening series and did not return. Based on what we saw from backup quarterback Seneca Wallace, it will be incredibly difficult for the Packers' offense to function at anything close to a high level in the passing game. The loss dropped them to 5-3 and into a three-way tie for first place in the NFC North with the Bears and the Detroit Lions.
Stock Watch: So the Packers' running game is for real. Even without much threat of a passing game, the Packers still ran the ball at will. After Rodgers left the game, James Starks had a 32-yard touchdown run, and Eddie Lacy ripped off a 56-yard run in the third quarter to set up his 1-yard touchdown run that tied the game at 17-17 with 13 minutes, 8 seconds left in the third quarter. The Packers rushed for a season-high 199 yards, including 150 by Lacy on 22 carries.
Gutsy call: After Lacy's game-tying touchdown, coach Mike McCarthy made the bold decision to try an onside kick, which worked to perfection. Mason Crosby hit the kick that was recovered by Packers linebacker Jamari Lattimore. The Packers turned that into a field goal that gave them a 20-17 lead.
Injuries galore: Rodgers wasn't the only player the Packers lost to injury. Right guard T.J. Lang sustained a concussion and did not play in the second half. Right tackle Don Barclay moved to right guard, while Marshall Newhouse came off the bench to play right tackle. Linebackers Andy Mulumba (ankle) and Sam Barrington (hamstring) also were injured.
What's next: The Packers host the Philadelphia Eagles on Sunday at Lambeau Field.
