The Oakland Raiders have released Trent Richardson.
Oakland gave Richardson $600,000 in guaranteed money this offseason after the Indianapolis Colts cut him.
Richardson had 19 yards on five carries in Sunday's preseason game.
Richardson, 25, was the No. 3 overall draft pick by Cleveland in 2012. He was traded a year later to the Colts for a first-round pick. In three NFL seasons he has averaged 3.3 yards per carry.
