49ers' Upton Stout: Done for night

Stout (concussion) will not return to Sunday night's game against the Bears, Eric Branch of the San Francisco Chronicle reports.

Stout banged his head on the turf in the second half against Chicago and will now presumably land in concussion protocol. Prior to exiting, Stout recorded four tackles (three solo). Chase Lucas is next up at slot cornerback for the Niners.
