Cardinals sign former Steelers QB Dennis Dixon to practice squad

TEMPE, Ariz. -- The Arizona Cardinals didn’t wait long to sign another quarterback.

The Cardinals signed Dennis Dixon to their practice squad Tuesday, giving them another option to back up Logan Thomas should Carson Palmer or Drew Stanton not return from their respective injuries this week.

On Monday, Cardinals coach Bruce Arians said he wanted any quarterback signed to be familiar with his offensive scheme and understand the protections. Dixon fits that. Drafted by the Pittsburgh Steelers in 2008, Dixon spent his first four years in the NFL playing for Arians, who was Pittsburgh’s offensive coordinator. Dixon learned Arians’ scheme but played in it just four times, throwing for 402 yards, two interceptions and one touchdown on 35-of-59 passing.

But as Stanton has proved this season, a quarterback doesn’t need to play in Arians’ offense to understand it.

Since spending parts of the 2012 season on the Baltimore Ravens' practice squad, he’s also spent time with the Philadelphia Eagles and Buffalo Bills.

In other moves, Arizona placed punter Dave Zastudil on injured reserve, placed outside linebacker Matt Shaughnessy on injured reserve/designated to return, re-signed linebacker Marcus Benard and promoted punter Drew Butler from the practice squad.
