Mitchell (ribs) was limited at Thursday's practice, Jennifer Lee Chan of NBC Sports Bay Area reports.
After not practicing at all Wednesday, Mitchell was on the field one day later wearing a blue non-contact jersey, which signaled the 49ers were capping his reps as he deals with a rib issue. Indeed, he operated under practice limitations, giving him one more chance to put in a full showing before week's end. Elsewhere in the backfield, JaMycal Hasty, Trey Sermon and Trenton Cannon avoided the injury report this week, while Jeff Wilson (knee) was designated to return from the reserve/PUP list. No matter, if Mitchell is available this Sunday, he'll be the 49ers' lead runner against the Cardinals.
