NFL free agency 2015: Arizona Cardinals add A.Q. Shipley to offensive line, announce Redding signing

The Arizona Cardinals announced another pair of signings on Wednesday, adding depth to the offensive and defensive lines. They signed center/guard A.Q. Shipley and defensive lineman Corey Redding to two-year contracts.

Redding's deal was already out there, but Shipley's was actually announced by the player himself on his Twitter account, in addition to the team announcement.

Shipley (6-1, 307) comes to Arizona after playing in 15 games with five starts last season with Indianapolis. He joined the Colts in 2014 after being claimed off waivers from the Baltimore Ravens on August 31. A versatile interior lineman, Shipley has played in 45 career games with 19 starts (10 at guard and nine at center).

The 28-year old Shipley entered the league with the Steelers as a seventh-round selection (226th overall) in the 2009 NFL Draft out of Penn State. After spending his first two seasons on the practice squads of the Steelers (2009) and Eagles (2010), Shipley signed with the Colts in 2012 and played in 14 games with five starts. The following season he was traded to Baltimore and played in 16 games with a career-high nine starts.

Shipley will be with Bruce Arians for the third time. Arians was offensive coordinator in 2009 when Pittsburgh drafted him. He was OC and interim head coach when Shipley was in Indy in 2012.

His signing gives the Cardinals a bunch of guys to play two positions. At center, they still have Lyle Sendlein, who has been the starter. Ted Larsen and Shipley, as well as second-year player Anthony Steen all can play center. Then, at right guard, there is Jonathan Cooper, Earl Watford, Larsen, Steen and Shipley to compete there.

Does this signing signal the likely release of Sendlein, whose contract is more than $4.2 million against the salary cap. The team could save more than $3 million by releasing him.
