The Tennessee Titans have brought back WR/KR Chris Davis due to the injury to Mark Jones.  Davis played in 17 games in 2007-2008 with the Titans and he caught 7 passes for 69 yards (9.9 avg).  The reason that the Titans brought him back however was his special teams play.  He has returned 33 punts for 299 yards (9.1 avg) and 6 kickoffs for 156 yards (26.0 avg) in his career and those are the roles he will likely fill with the Titans.  The Titans released CB Cary Williams to make room on the roster for Davis.  Williams played in 4 games this season for the Titans and he made 12 tackles and defensed 1 pass for them.  The Titans will likely re-sign Williams to the practice squad if he clears waivers.

UPDATE:  The Titans have cut Chris Davis after only three days as they like Alvin Pearman better to return kicks and punts.
