If Calvin Austin sits out games because of a shoulder injury, it will raise an all-too-familiar question for the Pittsburgh Steelers offense. “I was devastated when he went down, but from what I hear, he won’t be out long,” wide receiver Ben Skowronek said Tuesday. He took advantage of Austin’s absence with an abdominal injury in August to force his way onto the 53-man roster. I want to be the guy who can get the run game going.”The Steelers’ stable of tight ends also can be used to fill Austin’s void. They took a backseat to Darnell Washington and Connor Heyward while the Steelers were running for a season-high 131 yards.
