Rhodes was carried off the field last Sunday with about five minutes remaining after taking a shot to his back and did not return. He is expected to replaced in the lineup by Rashad Johnson with the Cardinals' pass defense taking a huge blow in the deep middle of the field.
Quarterback Kevin Kolb has also been ruled out for this Sunday's game as expected. Kent Somers of the Arizona Republic confirmed on Wednesday that Kolb should miss "at least 6-8 weeks" with a number of injuries that include a sprained sternoclavicular joint, three detached ribs and a sprained shoulder.
In related injury news, the Cardinals listed FB Anthony Sherman (knee) and CB Greg Toler (hamstring) as doubtful as neither have participated in practice all week, either.
As for players with the questionable tag, CB Michael Adams (hamstring), TE Todd Heap (knee) and LB Reggie Walker all have a 50-50 chance of playing. Of the three, Adams probably is the likeliest after turning in a full practice Friday.
The Cardinals also have DT Darnell Dockett (hamstring), LB Paris Lenon (knee) and LB Quentin Groves (hamstring) listed as probable for Sunday's NFC battle.
