SANTA CLARA, Calif. (AP) - San Francisco 49ers quarterback Alex Smith practiced again on Saturday, however his availability is still uncertain for the game against the Chicago Bears.
Smith suffered a concussion last week against the St. Louis Rams.
He still hasn't been cleared to play by doctors, and the 49ers (6-2-1) might not get a final verdict on his status until hours before Monday's NFC showdown against the Chicago Bears (7-2).
``Alex is still going through the protocol right now,'' offensive coordinator Greg Roman said Saturday. ``And that's in the doctor's hands. When we know, you will probably know.''
