The Giants have claimed rookie running back Gartrell Johnson off waivers from the Chargers.  He was a 4th round pick out of Colorado State.  Johnson was the leading rusher this pre-season for the Chargers and it was a surprise that he was cut.  Johnson carried the ball 48 times for 184 yards (3.8 ypc) this pre-season.  He also caught 7 passes for 57 yards (8.1 avg) for the Chargers.  Johnson will get the chance to battle for the #3 RB job with Danny Ware down with a injury.
