"The Steelers will be without center Maurkice Pouncey Monday night in San Francisco, but whether Ben Roethlisberger will be the one taking snaps from Doug Legursky is still a mystery.

Roethlisberger had limited participation in Saturday's and Friday's practices and is listed as questionable on the team's official injury report. Pouncey is out. Both sustained Grade I left high ankle sprains in the second quarter of a 14-3 win Dec. 8 against Cleveland.

Offensive coordinator Bruce Arians said earlier in the week that if Roethlisberger cannot play, Charlie Batch will start at quarterback."
