From ProFootballTalk.com: In the wake of losing running back Marcus Murphy to injured reserve, the New Orleans Saints once again looked to free agency for additional backfield help. The Saints signed former San Francisco 49ers running back Kendall Hunter on Wednesday. In addition, the team promoted fullback Toben Opurum from their practice squad, signed defensive back Tony Carter and placed defensive back Damian Swann on injured reserve. Hunter missed the entire 2014 season after suffering a torn ACL. He appeared in two games this preseason for San Francisco – carrying 17 times for 36 yards – before again being placed on injured reserve.
