The Jaguars couldn't get much of a rushing attack going during a 17-9 loss Week 5 vs. Pittsburgh. 

Starting running back Toby Gerhart turned in another disappointing performance, rushing for 9 yards on four carries. He has just 123 rushing yards through five games.

Backup running back Denard Robinson wasn't much better Sunday, rushing for 6 yards on three carries. 

Surprisingly, the Jaguars leading rusher was rookie Storm Johnson, who received the first carries of his NFL career Sunday. He rushed for 27 yards on four carries.

Gerhart added one catch for 20 yards and Robinson had two catches for minus-1 yards. The Jaguars are back in action Week 6 at Tennessee.
