Grant (concussion) has been ruled out for Sunday's contest at Seattle.
Grant left Monday's game against the Vikings after suffering a concussion, and he has yet to gain clearance to return. His absence will be most felt on special teams, though he has seen increased snaps as a receiver of late due to the depletion of healthy Bears wideouts. Khalil Herbert should handle kick returns while Damiere Byrd figures to take over punt returns in Grant's absence.
