Quitoriano signed to the Cardinals' practice squad Monday, Zach Gershman of the team's official website reports.
Quitoriano spent training camp with Arizona but was released Monday. However, the team decided to keep him around as depth on the practice squad. Quitoriano played in all 17 regular-season games for Atlanta last year and logged 131 offensive snaps, though he was used exclusively as a blocker, as he didn't garner any targets or touches.
