49ers HC Jim Harbaugh has informed Alex Smith that Colin Kaepernick will start Sunday, per source. Said decision not based on health.
Update: A Tweet from ESPN indicated that Smith spoke on the phone with Trent Dilfer and that Smith said the only decision was that Kaepernick would get the first-team practice repetitions at the beginning of the week. The Tweet: "Alex Smith just told @TDESPN that Harbaugh told him Kaepernick would get 1st team reps but door open to start game based on practice."
Kaepernick is a sneaky start this week against the Saints, who have been very generous to opposing QBs this season. He is currently our #13 QB for Week 12. He has mediocre-to-good matchups against the Rams, Dolphins and Patriots before a bad matchup against the Seahawks in Week 16.
