The Lions have decided to bring back WR/KR Adam Jennings.  The 26-year old Jennings played in 14 games for the Falcons and Lions last season and he returned 24 punts for 151 yards (6.3 avg).  In his three year NFL career, Jennings has played in 45 games in which he has caught 6 passes for 62 yards (10.3 avg) with 1 TD grab.  Jennings has also returned 54 punts for 337 yards (6.2 avg) and 24 kickoffs for 551 yards (23.0 avg) in his career.  The Lions will no doubt use Jennings to return kickoffs and punts as they are not satisfied with those units right now.
