Cardinals running back Andre Ellington (knee) was limited at practice Wednesday, Darren Urban of the Cardinals' official site reports.
As expected, Ellington is kicking off preparation for Sunday's game against the Rams with a limited practice, which may forecast his activity level throughout the week. As his recovery from a sprained PCL continues, his practice reps may not give a good indication of his potential to play in Week 4.
If he remains sidelined, Chris Johnson will head the backfield yet again, with David Johnson filling a change-of-pace role.
