The quarterback controversy is underway in San Francisco after quarterback Colin Kaepernick's superb performance last night against Chicago, one that brought praise even from Bears All-Pro linebacker Brian Urlacher.

It was Kaepernick's first career start, serving in the place of Alex Smith who this morning is still suffering post-concussion effects. Kaepernick threw for a modest 243 yards and two touchdowns, while shepherding the 49ers offense on several long, clock-eating drives. When asked afterward if Kaepernick had proven himself worthy of the starter's role, Jim Harbaugh provided a characteristic non-answer:

Kaepernick's been solid in previous appearances as Smith's backup (35-54 overall, with no interceptions) and upcoming appearances against the Saints and Rams should allow the second-year QB some room to breathe if Harbaugh sends him out on the field again; of course, Harbaugh's choice becomes a bit easier if Smith's alleged blurred vision, headaches and nausea continue.
