Steelers rookie quarterback Josh Dobbs will start tomorrow at MetLife Stadium against the Giants. Ben Roethlisberger will rest for the first preseason game, and primary backup Landry Jones is dealing with an abdominal injury. Coach Mike Tomlin wants to see Dobbs’ game-day demeanor and communication with coaches and players. Coach Tomlin also said he’s remained in contact with running back Le’Veon Bell as he trains in South Florida. Bell has yet to report to camp and sign his $12.1 million franchise tender. The team said Bell should arrive to camp later this month.
