According to Bruce Arians, Cardinals running back Andre Ellington (knee) was almost healthy enough to play Sunday against the Rams.
Ellington practiced on a limited basis leading into Week 4, but the relative health of both Chris and David Johnson spurred Arians to exercise caution with his presumed No. 1 running back. If he continues to progress this week, Ellington should take the field Sunday at Detroit, but his workload would be contingent upon the state of his knee.
