The Arizona Cardinals have another injury to a key player to worry about, but they got some good news on Saturday. Running back Andre Ellington returned to practice on a limited basis Saturday after undergoing an MRI on his foot earlier in the week. Coach Bruce Arians said he was optimistic Ellington will play. NFL Media Insider Ian Rapoport reported Friday that Ellington will not require surgery on the foot. Ellington's injury is the latest in a string of setbacks for Arizona. Defensive lineman Darnell Dockett is out for the season with a torn ACL and inside linebacker Daryl Washington is suspended for the season. NFL.com
