Austin was originally drafted in the second round of the 2011 NFL Draft out of the University of North Carolina despite not playing his senior season. After being viewed as a potential Top 10 draft selection in 2010, Austin was suspended, along with Greg Little and Robert Quinn, for receiving improper benefits.
The 6-1, 309-pound tackle was viewed as a near complete package at the three-technique. Austin could rush the passer and stuff the run, but neither abilities were displayed during his injury-filled tenure in blue. In his rookie season, Austin tore his pectoral muscle on Aug. 22. In 2012, he appeared in just eight games registering five tackles and three assists.
The Giants released Austin during the final cut-down day of training camp last year. He signed with the Miami Dolphins on Sept 24, but was cut on Oct. 15. Austin joined the Dallas Cowboys on Oct. 21, before being cut on Nov. 5.
Austin appeared in one game with Dallas, registering one tackle. Over the last two seasons, the Washington D.C. native has appeared in 11 games and has a combined seven tackles.
