The 49ers have signed DeShaun Foster to a 2-year contract.  Foster played in 16 last season for the Panthers and he carried the ball 247 times for 876 yards (3.5 ypc) with 3 TD runs.  He also caught 25 passes for 182 yards (7.3 avg) with 1 TD grab.  Foster has now played in 63 games in his NFL career and he has carried the ball 851 times for 3,336 yards (3.9 ypc) with 10 TD runs.  He also has caught 126 passes for 996 yards (7.9 avg) with 4 TD grabs.  It will be nice this season for the 49ers to be able to give Frank Gore a breather from time to time to keep him fresh and healthy.  I really like this move for the 49ers.
