The Tennessee Titans have signed veteran running back Jackie Battle and tight end DeMarco Cosby on Wednesday.
To make room on the roster, Tennessee released running back Alvester Alexander and quarterback Nathan Enderle.
Battle is a five-year NFL veteran with the San Diego Chargers and Kansas City Chiefs. His best year came in 2011 when he ran for 597 yards for the Chiefs.
Cosby, an undrafted free agent from Central Missouri in 2011, has spent time on the practice squads of the Rams, Packers and Chiefs. The Titans needed him with Delanie Walker going on PUP to start camp due to a knee injury.
