Offensive guard Harvey Dahl has returned to St. Louis Rams practice after missing four games with a left knee injury and expects to play Sunday at Arizona.
Dahl was injured in the third quarter of Week 8 against Seattle. The Rams (5-7) lost a starting lineman when center Scott Wells broke his left ankle Sunday at San Francisco.
Running back Zac Stacy (foot) did not practice Wednesday along with offensive tackle Jake Long and backup linebacker Darren Bates, both with concussions.
Defensive end Eugene Sims (neck) was limited.
