Arkin, 28, is a former fourth-round pick of the Cowboys back in 2010. He spent just over two years in Dallas before he was waived during the 2013 season.
Since then, Arkin has played for a number of teams including the Dolphins, Seahawks and Colts before signing onto the Rams’ practice squad last year. The Rams elected to bring him back on a future/reserve contract this past January.
In 2013, Arkin appeared in two games for the Dolphins.
