Cardinals starting center A.Q. Shipley went down after suffering an injury during the Red and White practice on Saturday.
He was able to walk off the field, though limping, and athletic trainers tended to him in a pop-up tent on the sideline.
After about five minutes in the tent, he was carted off, wearing a towel over his head. He has not returned.
Larry Fitzgerald and D.J. Humphries both checked on Shipley while he was in the tent.
