Herbig is managing an undisclosed injury and may not suit up for Saturday's preseason contest against Buffalo, Ray Fittipaldo of the Pittsburgh Post-Gazette reports.
The nature of Herbig's injury hasn't been shared, though head coach Mike Tomlin didn't seem to consider it serious, calling the issue a "training camp level injury," per Nick Farabaugh of Penn Live. Herbig is slated to work as the Steelers' starting center this season, but Zach Frazier ran with the starting offense in his place at practice Thursday.
