Cards' Boldin to undergo MRI

TEMPE, Ariz. (AP) -- Three players who fill significant roles for the Arizona Cardinals are nursing injuries heading into the postseason.

Wide receiver Anquan Boldin has a sprained left ankle, defensive end Calais Campbell a broken left thumb and cornerback Dominique Rodgers-Cromartie a bruised left kneecap.

Coach Ken Whisenhunt said Boldin was sore and undergoing an MRI on Monday.

Whisenhunt seemed optimistic that Campbell and Rodgers-Cromartie would be ready when Arizona hosts Green Bay in a wild card game Sunday. He was more vague about Boldin's status, pending Monday's exam.

All three were hurt in Sunday's 33-7 regular-season finale against the Packers.
