Ellington (quadriceps) isn't expected to play Sunday against the Rams in London, Adam Schefter of ESPN reports.
Ellington didn't practice all week, but is listed as questionable on the official injury report. The Cardinals' addition of Adrian Peterson prevented Ellington from picking up any carries in the Week 6 win over the Buccaneers, but Ellington is still regarded as the team's top pass-catching back. When Peterson leaves the field on passing downs Sunday, Kerwynn Williams or Elijhaa Penny could be called upon for additional reps out of the backfield.
