Packers running back Cedric Benson was seen leaving the locker room in a walking boot Sunday after suffering a left foot injury, but told the Milwaukee Journal Sentinel that "X-rays were negative and he thought it was just a mild sprain."Fantasy Spin:Benson might miss Week 6, but it appears that he may have avoided a more serious injury. He was just coming into his own in the Packers' offense and will be missed. He has rushed for 248 yards and one touchdowns and has caught 14 balls for 97 yards this season. Alex Green figures to be the starter if Benson misses any action.
