Jack (groin) was a limited participant at practice Friday and is considered questionable to play Sunday versus the Browns.
Jack missed last week's win over the Ravens as he continues to deal with a groin issue, and his status still remains up in the air for the Steelers' regular-season finale Week 18. The 27-year-old opened this week with two absences at practice before returning in a limited capacity Friday. If the linebacker remains unavailable Sunday, Robert Spillane will likely draw the start in his place against Cleveland.
