Poor Marcus Mason.  The Redskins decided to keep three running backs so he got the shaft.  Mason played in 5 games this preseason for the Redskins and he carried the ball 66 times for 317 yards (4.8 ypc) and he also caught 8 passes for 56 yards (7.0 avg) with 1 TD grab.  The Redskins won’t be able to add him to the practice squad as the Ravens signed him to theirs.
