Colin Kaepernick: More than a 49ers backup QB?

Aldon Smith took over the NFL sacks lead with 15, passing Denver's Von Miller with 13, and recorded the second-best total in franchise history behind Fred Dean's six-sack day on Nov. 13, 1983, against New Orleans. Tarell Brown and Dashon Goldson each had an interception for San Francisco's stingy defense, which shut down Campbell, Matt Forte and Co. three years after the teams last met in a 10-6 49ers home win.

"I think I have a thing for night games, I love playing at night," Smith said. "I love playing under the lights."

Kaepernick, Aldon Smith and Hunter sure made general manager Trent Baalke looked good for his selections from the 2011 draft class.

"Colin is the man!" Davis said emphatically. "Colin did a great job, I was very proud of him."

And reigning NFL Coach of the Year Harbaugh earned a key victory four days after his own health issue. The 48-year-old Harbaugh had a minor procedure for an irregular heartbeat Thursday.

The 49ers added a safety in the fourth quarter after a replay review. With 9:24 left, former San Francisco offensive lineman Chilo Rachal was called for intentional grounding out of the end zone, but Harbaugh challenged and the review showed Rachal's knee was down in the end zone before the ball left.

"Tonight was probably the worst nightmare. We just have to find a way," Campbell said. "It's one game that we lost. We have to pick it back up next week and try to get back on the winning side. Our goals and everything still sit ahead of us."

The soft-spoken, stone-faced Kaepernick went 16 for 23 with a 133.1 passer rating. He completed 12 of his first 14 passes with a 57-yard strike to Kyle Williams that set up Davis' 3-yard TD on the next play — and he already had amassed 126 yards passing by the end of the first quarter.

The 49ers led 17-0 on Hunter's early TD run in the second, quickly topping the 14.8 points the Bears were allowing per game.

Kaepernick threw for 184 yards in the first half alone — an impressive outing for the second-year pro selected in the second round out of Nevada.

"I think after the first drive I felt really comfortable with what they were doing and what we had in our game plan," he said. "I really wasn't too nervous. I've had a lot of time in this offense. My teammates were really supportive."

Frank Gore ran for 78 yards and David Akers kicked field goals of 32, 37 and 32 yards for the 49ers, eager to defend their home field a week after settling for a frustrating 24-24 tie against the division rival St. Louis Rams.
