Cox played in 18 games for the Giants over two seasons, 14 as a rookie and four last season. He started the 2014 season on the practice squad, was activated, then finished the season on injured reserve after suffering a fractured leg.
In two seasons with the Giants, Cox carried the ball 26 times for 76 yards (2.9 yards per carry), caught five passes for 21 yards and returned 31 kickoffs for an average 22.5 yards per return.
The Giants currently have five tailbacks on the roster -- Rashad Jennings, Andre Williams, Shane Vereen, Orleans Darkwa and Chris Ogbannaya.
There has been some recent speculation that the Giants might be interested in Georgia running back Todd Gurley with the ninth overall pick. Even if that is not the case, the 2015 NFL Draft class is considered deep at the running back position, so the Giants could add a player in the middle to late rounds.
