Miami Dolphins add free agent DL Marvin Austin

It's been a rough week along the defensive line for the Miami Dolphins, with Paul Soliai missing the game against the Atlanta Falcons with a knee injury and Cameron Wake having to leave the game with his own knee problems.  As the Dolphins prepare to face the New Orleans Saints on Monday Night Football, the team has to be concerned about the depth of the line as player after player seems to be getting hurt.

Wake is expected to miss 2-3 weeks with a sprained MCL in his left knee.  The injury to Soliai, and how long he may miss, is unknown other than it's his knee.

To bolster the defensive line's depth, the Dolphins signed free agent Marvin Austin today, according to a report from Jason La Confora.  Austin was a second round pick of the New York Giants in 2011 after a college career at North Carolina.  The defensive tackle spent his rookie season on injured reserve after tearing his pectoral muscle in a preseason game.

He appeared in seven games last season with the Giants, recording eight tackles.  He was waived by the Giants during the preseason this year.

With Wake likely out, and the news of the Austin signing signaling the likelihood that Soliai will miss the game this week as well, the Dolphins will look to defensive ends Olivier Vernon, Derrick Shelby, and Dion Jordan at defensive end, while Jared Odrick and Randy Starks will be the primary defensive tackles.

It's not known at this time who the Dolphins released to make space for Austin on the roster.
