Drew Butler was promoted from the Arizona Cardinals practice squad to replace punter Dave Zastudil on Tuesday. Zastudil landed on injured reserve with a groin injury.

To replace Butler on the practice squad, the Cardinals signed former Bruce Arians pupil Dennis Dixon to the practice squad. The former Steelers quarterback provides insurance in the event Carson Palmer and backup Drew Stanton (concussion) are not available for Sunday’s game against the Washington Redskins.

Palmer remains week-to-week with a shoulder injury.

Butler replaced Zastudil for the first three games of the season and had a 36.0-yard net on nine punts.

Linebacker Matt Shaughnessy (knee) was placed on injured reserve with a designation for return. Veteran Marcus Bernard was re-signed to the active roster to fill Shaughnessy’s roster spot.
