Kerwynn Williams

The Cardinals got Andre Ellington back at practice Monday, but that wasn’t enough to make coach Bruce Arians feel confident that they have enough in the backfield.

Ellington missed time with a hamstring injury, which is the same reason that rookie David Johnson has been out since early in training camp and also why Marion Grice has been on the sideline. Stepfan Taylor and Kerwynn Williams have been active, but Arians said, via the team’s website, that he was “not fired up about the running backs’ performance on Saturday.”

While talking to the media, Arians said he and General Manager Steve Keim would discuss other possibilities. Arians was asked if former Ravens running back Ray Rice would be one of the players up for discussion, but the Cardinals coach said, via Josh Weinfuss of ESPN.com, that the team isn’t considering him.

Pierre Thomas, Steven Jackson and Chris Johnson are other veteran options that could land on Arizona’s radar and the team could also explore a trade if they decide to move forward with an outside addition to the group, the story said.
