Arizona Cardinals injury report: William Powell in full pads on Wednesday

Arizona Cardinals running back William Powell will likely play on Sunday against the Buffalo Bills at University of Phoenix Stadium after turning in a full practice on Wednesday while dealing with a head injury he suffered in Week 5.

Powell's status was a big concern for Cardinals fans because of the team's lack of depth at the position following significant injuries to Beanie Wells and Ryan Williams that landed each on injured reserve. Powell will likely be called upon to shoulder much of the rushing load moving forward in their absence.

Also returning to the practice field was quarterback John Skelton, who also practiced after a Week 1 ankle injury saw him miss the team's previous four games. Initially tabbed as the Cardinals starting signal caller, it's unclear whether or not he'll regain his role once he's cleared to play. Offensive lineman Adam Snyder also practiced fully.

Darnell Dockett (hamstring), Jim Dray (knee), Todd Heap (knee), O'Brien Schofield (knee) and LaRod Stephens-Howling (hip) were each limited during the Wednesday session. Michael Adams (hamstring), Quentin Groves (hamstring), Anthony Sherman (knee), Greg Toler (hamstring) and Reggie Walker (head) were held out.
