linebacker Isaiah Irving was carted off the field during Sunday's game against the Seattle Seahawks with a neck injury.
The Cardinals announced he was ruled out for the remainder of the contest.
Irving was blocking during a potential kickoff return in the first half and was injured when he hit running back Travis Homer on the play. Players on both teams dropped to a knee during the lengthy delay before some of the players came over to the cart to wish him well.
Irving, who was an undrafted rookie out of San Jose State, was a member of the Chicago Bears for the last three seasons.
