PITTSBURGH—Steelers rookie tackle Marcus Gilbert will miss Sunday's game against the Jacksonville Jaguars (1-4), meaning Pittsburgh (3-2) will start its sixth different combination of offensive linemen in six games.
Former starting left tackle Jonathan Scott will start in Gilbert's place on the right side. Gilbert injured his right shoulder three weeks ago in a win at Indianapolis and aggravated the injury last week against Tennessee. Scott -- since replaced at left tackle when Max Starks was signed last week -- came in for Gilbert at right tackle.
Third-down running back Mewelde Moore also was ruled out for Sunday, meaning those duties will fall to Isaac Redman or Jonathan Dwyer. Redman started last week in place of Rashard Mendenhall, who will return. In his second career game, Dwyer had 107 rushing yards.
