The Cardinals will officially be without one of their key depth pieces on the offensive line after putting swingman Justin Murray on injured reserve on Friday.
Murray has been dealing with a back injury suffered in Jacksonville in Week Three. He can return, but he will miss at least three games -- this weekend against the 49ers, Oct. 17 in Cleveland, and Oct. 24 against Houston.
Murray had been playing right tackle in place of Kelvin Beachum, but against the Jaguars he was moved inside to right guard with right guard Josh Jones moving to right tackle.
Murray didn't practice this week and had already been listed as out for Sunday. Coach Kliff Kingsbury said Beachum, recovering from his ribs issue, is a game-day decision. If Beachum can play, Jones moves back to right guard. If Beachum can't play, Jones will stay at right tackle with capable fill-in Max Garcia remaining at right guard.
