Cardinals running back Andre Ellington is listed as the Cardinals' No. 2 running back in advance of Sunday's contest at Pittsburgh, Josh Weinfuss of ESPN.com reports.

Ellington suffered a sprained PCL in Week 1 and subsequently logged three consecutive DNPs. His absence allowed Chris Johnson to take over the gig, as the veteran cruised to 405 rushing yards in the first five games. While Ellington returned Sunday in Detroit, he received just three carries, as opposed to 11 for Johnson and three for rookie David Johnson, including two goal-line reps.

Ellington is poised to take on a change-of-pace role behind workhorse Chris Johnson for now, but his weekly tallies will likely be dependent on taking efficient use of his mix of rushes and receptions.
