Running back Jackie Battle signed a one-year deal with the Chargers after spending his first five NFL seasons with division-rival Kansas City.
An undrafted rookie out of Houston in 2007, Battle rushed for 597 yards and two touchdowns last season. He has rushed for 715 yards on 190 career carries.
He joins a backfield led by Ryan Mathews. The Chargers signed veteran Ronnie Brown this offseason and also have third-year player Curtis Brinkley and rookies Edwin Baker and Michael Hayes set to come to training camp.
The Chargers also released fullback Mohamed Marah. They have Jacob Hester and Le'Ron McLain on the roster.
