Bears at 49ers
8:30 p.m., ESPN
Line: 49ers by 6.
The skinny: When Chicago quarterback Jay Cutler got hurt last November, the Bears' promising season fell apart with no capable backup behind him.
The Bears went from 7-3 to losing five of their final six, finishing 8-8. Chicago acquired an insurance policy during the offseason, and now the Bears (7-2) will see whether that move pays off. Jason Campbell is set to make his first NFL start in more than a year in place of Cutler (concussion) in a key NFC showdown with San Francisco (6-2-1) at Candlestick Park.
