From the Associated Press:

TEMPE, Ariz. (AP) Arizona Cardinals starting linebackers Gerald Hayes and Chike Okeafor are doubtful for Sunday's game against NFC West foe Seattle.

Neither has practiced this week because of back injuries. Hayes would miss his second straight game.

Ali Highsmith started in place of Hayes at inside linebacker last week. Bertrand Berry is Okeafor's backup at outside linebacker.

Starting left tackle Mike Gandy (pelvis) was listed as questionable after being limited in practice Friday. If Gandy can't play, it would break a string of 28 consecutive games that Arizona has had the same offensive line. Jeremy Bridges is his backup.
