PITTSBURGH — Steelers quarterback Ben Roethlisberger was limited in practice Friday, while safety Troy Polamalu and center Maurkice Pouncey sat out.

Coach Mike Tomlin and offensive coordinator Bruce Arians both said they’d like Roethlisberger practice at least once before they decide whether he’ll play Monday at San Francisco. He sat out three straight practices before participating Friday.

If Roethlisberger can’t play, 37-year-old Charlie Batch will start..

Along with Polamalu (hamstring) and Pouncey (ankle), linebacker Chris Carter (hamstring) and receiver Emmanuel Sanders (foot) did not practice. Polamalu is expected to play vs. the 49ers.
