Boldin's status for Sunday is unknown

TEMPE, Ariz. -- Cornerback Dominique Rodgers-Cromartie has returned to practice for the Arizona Cardinals, but wide receiver Anquan Boldin remains sidelined with a sprained left ankle.

Although he was listed as limited in Thursday's workout, Rodgers-Cromartie says he was at full speed and felt good. He missed practice Wednesday because of a bruised left kneecap.

Boldin says he doesn't know if he will be able to play in Sunday's wild card game against Green Bay.

Defensive end Calais Campbell practiced with a club-like cast on his broken left thumb. Starting right guard Deuce Lutui didn't practice after leaving Wednesday's workout with back spasms.

Starting safety Antrel Rolle, who missed last Sunday's game with an injured right thigh, practiced on a limited basis.
