According to the St. Louis Post-Dispatch, Steven was back at practice today in limited action. As written in the Around the Horns blog:

Steven Jackson took part in most drills today during practice at Rams Park, taking about a third of the snaps with the first team. Jackson missed last Sunday’s game at New England with a strained thigh muscle, and Antonio Pittman started at running back.
