Steelers' Isaac Seumalo: Leaves with shoulder issue

Seumalo (shoulder) is questionable to return to Sunday's game against the Cardinals, Ray Fittipaldo of the Pittsburgh Post-Gazette reports.

Pittsburgh's starting left guard is on the sideline getting his shoulder looked at by the team's medical staff. Nate Herbig is likely the next man up to replace Seumalo along the Steelers' offensive line.
