QB Carson Palmer (ankle sprain) didn't practice on Wednesday but is expected to play. He suffered the injury during last week's game but didn't miss a play.
S Rashad Johnson (high ankle sprain) isn't likely to play so rookie Tony Jefferson could get his first start. The Cardinals will miss Johnson's experience.
WR Larry Fitzgerald (concussion) missed practice time this week as he went through the NFL's protocol for players with head injuries. Fitzgerald expects to play but it's no sure thing. If he can't play, Michael Floyd will assume his spot, with Andre Roberts moving into the starting lineup.
WR Michael Floyd (shoulder/ankle) is playing through significant injuries. The shoulder injury happened weeks ago and hasn't affected him that much in games. The ankle, however, seemed to bother him last week against the Rams.
