The Arizona Cardinals came out of the Rams game relatively healthy but there is one concern with Ali Highsmith. He's having an MRI today but he was on crutches last night with his leg immobilized. This looks like it could be season ending injury and if it is, that's a blow to the coverage units considering Highsmith has been one of the leading tacklers on special teams. If he is placed on IR, we'd likely see one or two corresponding roster moves, including a possible return to the roster for Chris Harrington.
