Drew Stanton was carted off the filed in the Arizona Cardinals' 12-6 win over the St. Louis Rams with a knee injury.

The Cardinals have already lost Carson Palmer for the season due to injury.

"We know he has a knee injury," Bruce Arians said. "We have no idea what the extent of it is. He's had a previous one, so there's not any knowledge whatsoever.

"We'll take it very slow with him and see how it goes once we get in the MRI and all that information."

Ryan Lindley took over for Stanton at quarterback instead of Logan Thomas.
