SAN FRANCISCO – In a game billed as the battle of the backup quarterbacks, Jason Campbell and the Chicago Bears were shut down Monday night by a dominant San Francisco defense in a 32-7 loss that dropped the Bears into a tie with the Green Bay Packers atop the NFC North.

The Bears' record fell to 7-3 while the 49ers improved to 7-2-1. The Packers also are 7-3 and at present own the tiebreaker by virtue of their Week 2 victory over the Bears. Next up for the Bears is a home game against Minnesota at noon Sunday.

"We're disappointed in this loss, but it does count as just one loss," coach Lovie Smith said. "We're a 7-3 team right now with a big game coming up against Minnesota."
