Smith signed with the Raiders in December 2019 and played in three games. But the team since added Devontae Booker, Lynn Bowden Jr. and Theo Riddick to a backfield already housing Josh Jacobs and Jalen Richard.
Smith, 28, is a vested veteran and will return to free agency. He is best known for his years backing up Ezekiel Elliott in Dallas but has been on three teams — the Giants, Titans and Raiders — since 2019.
Las Vegas also re-signed Devey this offseason, bringing back the former 49ers and Chiefs lineman in April. However, the Raiders drafted guard John Simpson in the draft a few weeks later. They still have starters Gabe Jackson and Richie Incognito, with Simpson and Denzelle Good supplying depth. A six-year veteran, Devey played in four Raiders games last season before heading to IR with a torn pectoral muscle.
