Rams running back Zac Stacy still hasn't been cleared for contact following his Week 12 concussion, but he took a step forward as he practiced Thursday one day after not practicing at all. Benny Cunningham is waiting in the wings if Stacy is unable to play this weekend versus the 49ers.
Stacy is going through a process, and I doubt that we will know for sure if he'll play in Week 13 before Saturday. But he is making progress and seemingly has a good chance of being available as long as he doesn't suffer anymore post-concussion symptoms. The hope is he will be cleared for contact in the next couple of days. Stacy would be a high-end RB2 if he plays, even against the Niners' staunch defense.
