The Bengals have signed 26-year old WR Chris Davis.  Davis did not play in the NFL last season.  He has played in 17 games in his NFL career in which he has caught 7 passes for 69 yards (9.9 avg) and he has also carried the ball 2 times for 19 yards (9.5 ypc).  Davis has also returned 33 punts for 299 yards (9.1 avg) and 6 kickoffs for 156 yards (26.0 avg).  The fact that Davis plays a lot on special teams will help his chances of making the Bengals’ roster in 2010.
