Running back Kevin Smith and tight end Brandon Pettigrew have been ruled out of Saturday night’s preseason opener along with eight others. Coach Jim Schwartz announced the names on Friday.

Smith and Pettigrew had a small chance to play, but both are coming off ACL surgery and both have been eased into training camp. Schwartz would rather err on the side of caution than throw players in when they are not ready.

Safety Louis Delmas, who practiced Monday through Wednesday after coming back from a groin injury, was ruled out Thursday.

Other injured players who will not take the field at Pittsburgh include: kicker Jason Hanson, linebacker DeAndre Levy, defensive end Jared DeVries, cornerback Aaron Berry, wide receiver Mike Moore and the two who remain on the physically unable to perform list -- cornerback Jack Williams and safety Ko Simpson.
