FLAGSTAFF, Ariz. (AP) -- The Arizona Cardinals are down to two quarterbacks after Max Hall injured his shoulder.

Coach Ken Whisenhunt says Hall's injury, a subluxation or partial dislocation, is the same as the one that sidelined him late last season. Hall, in a fight to make the opening roster, was sent to Phoenix for further evaluation.

Backup quarterback John Skelton is wearing a walking boot on his right foot for what Whisenhunt says appears to be a high ankle sprain.

That left only Kevin Kolb and Richard Bartel for Tuesday's practice. The team is expected to add a third quarterback for Saturday's preseason game against San Diego.
