According to CSN Bay Area's Matt Maiocco, if Smith is cleared to play he will start for the 49ers, and all indications point to Smith being cleared to play.
Jim Harbaugh had this to say about Smith's situation on Monday:
"(He's) doing much better, had a good night's sleep last night," Harbaugh said. "And symptoms are positive today. He's visiting with a neurologist later this afternoon."
"Our doctors were good," Harbaugh said. "They were very proactive on that hit. They watched it on the monitors, and Alex had no symptoms after that hit. He was cleared to play. And then it appears it was the quarterback sneak, where he comes up and had blurred vision and that's when we brought in Colin immediately.Judging by the way Colin Kaepernick played on Sunday, albeit under intimidating circumstances, it would not take much for the 49ers to play Smith on Monday Night Football.
However, Harbaugh and his staff have encountered quite a predicament this week. Smith is not likely to practice the entire week, and with Kaepernick healthy it would behoove the 49ers to have a full week of practice with a definitive starting quarterback before encountering the most impressive defense the 49ers will face all season in the Bears.
As Maiocco mentioned, Harbaugh is not likely to reveal much this week, other than revealing whether or not Smith will be cleared to play on Monday night -- which should be revealed within the next couple of days.
The speculated "quarterback controversy" between Smith and Kaepernick could work in the 49ers' favor in this instance. Smith is obviously the 49ers' undoubted starter, despite a rather impressive game by Kaepernick given the circumstances. The Bears will not know which quarterback to prepare for this week, and given Harbaugh's reluctance to reveal anything to the media, Chicago may not know until game-time on Monday.
