Chicago at San Francisco
Time: 8:30 (ESPN)
Records: Bears (7-2), 49ers (6-2-1)
The skinny: Bears have won four of last six meetings with Niners since being shut out 17-0 at Candlestick Park on Dec. 17, 2000. 49ers lead NFL in fewest points allowed (14.1), while Bears are second (14.8). ... Jason Campbell will start at QB with starter Jay Culter out with a concussion. San Francisco could start QB Colin Kaepernick because Alex Smith also suffered a concussion last week. Kickers on both sides missed key opportunities last week: David Akers a 41-yarder in OT for Niners, Robbie Gould a 48-yarder early in fourth quarter at home vs. Houston. Chicago WR Brandon Marshall has 51 catches for 690 yards and six TDs in past six games. San Francisco RB Frank Gore has five TDs for season and 48 for career, leaving him two TDs rushing shy of matching late Hall of Famer Joe Perry and RB Roger Craig for most in franchise history.
