Roethlisberger questionable, Pouncey out

Steelers quarterback Ben Roethlisberger (ankle) is questionable after practicing on a limited basis for a second straight day, but Pro Bowl center Maurkice Pouncey (ankle) has been ruled out for Monday night's game at San Francisco.

Two other Steelers -- wide receiver Emmanuel Sanders (foot) and linebacker Chris Carter (hamstring) -- will also not play against the 49ers.

Strong safety Troy Polamalu (hamstring) is probable after a full practice today. He missed practices on Thursday and Friday. Right tackle Marcus Gilbert (illness) is also probable after full practices Friday and Saturday.
