Ellington (toe) is listed as active Sunday versus the Seahawks, Mark Dalton of the Cardinals' official site reports.
A Cardinals win in Week 17 must coincide with a Panthers loss to the Buccaneers in order to achieve home-field advantage throughout the playoffs. However, if the Panthers hold a noticeable lead early in the game, it may be enough to spur head coach Bruce Arians to sit David Johnson and Ellington in order to preserve them for future weeks. If the preceding comes to pass, the Cardinals would be down to Stepfan Taylor (shoulder) and Kerwynn Williams out of the backfield.
