The Oakland Raiders released running back Trent Richardson, according to multiple media reports.

Richardson, who was released by the Indianapolis Colts last season, signed with the Raiders in hopes of landing a spot on the 53-man roster. The Raiders, however, boast good depth at running back with Latavius Murray, Roy Helu, Taiwan Jones and Michael Dyer.

Richardson, the former No. 3 overall pick, has struggled since he was traded from the Cleveland Browns to the Colts for a first-round pick.
