Ellington was limited at Wednesday's practice due to a quadriceps injury, Darren Urban of the Cardinals' official site reports.
Ellington's production fell off a cliff with Adrian Peterson in the backfield Sunday, but the injury may have been to blame for no touches and only 13 offensive snaps. No matter, Ellington likely won't receive many carries moving forward, meaning he'll have to make his hay as a receiver. Without a significant snap count, he'll be hard pressed to put up consistent production.
