Irving, TX (SportsNetwork.com) - The Dallas Cowboys have signed defensive tackle Marvin Austin.

Austin, selected 52nd overall by the Giants in the 2011 draft, was released by Miami on Oct. 15. He was signed by the Dolphins on Sept. 24 and only played in two games.

The injury-prone lineman appeared in just eight games over his two seasons with the Giants, spending his entire rookie campaign on IR and making eight tackles as a reserve last year.

The 24-year-old Austin also sat out his senior season at the University of North Carolina in 2010, having being suspended for receiving improper benefits following an extensive NCAA investigation of the Tar Heels' program.
