Alex Smith (concussion) was officially limited in Wednesday's practice.
Smith has yet to be cleared for contact, but that could happen as early as Thursday. He will be active for Week 12, the question is, will he start. Coach Jim Harbaugh wasn't forthcoming on Wednesday. "We'll get all the factors weighed out. And we'll talk about it. And we'll come to the best decision for our team." The smart money remains on Colin Kaepernick, but Harbaugh has left the door open for both to play against the Saints. We may not get a definitive answer before Sunday.
