The Arizona Cardinals are not looking like the popular sleeper they once were in the NFC. A few losses has caused the team concern, one of those losses being running back Andre Ellington. The potential loss of Ellington for "extended time" would be the biggest concern yet.

Ellington was listed on the injury report with a foot issue on Thursday will undergo an MRI and may sit out an "extended" period of time.

Many fantasy scouts claimed that Ellington would have a huge breakout season after a quite impressive rookie season where he rushed for 654 yards with one touchdown over 15 games.

The Cardinals do not have much of a run game now. Their options are Jonathan Dwyer and Stepfan Taylor.

Ellington is a running back who can change a game with one burst of speed. Losing him on top of key defensive losses would be a massive blow to the Cardinals team who have already lost Darnell Dockett and Daryl Washington just to name a few.
