The Raiders picked up a pair of players off the waiver wire on Sunday.
They grabbed guard Antoine McClain from Baltimore and defensive lineman Brian Sanford from Cleveland. They released punter Chris Kluwe and quarterback Tyler Wilson in corresponding moves.
McClain and Sanford add depth to thin position groups.
Sanford (6-foot-2, 280 pounds) is a third-year pro out of Temple who spent parts of two seasons on the Browns practice squad. He played six games over the last two seasons. He played just once in 2012. He has six total tackles and no sacks.
Sanford will join a rotation on the interior line that includes Pat Sims, Vance Walker, Christo Bilukidi and Stacy McGee.
McClain is a first-year player who spent last season on the Ravens' practice squad. McClain (6-5, 336) had offseason foot surgery, but competed throughout training camp. He’s better blocking the run than the pass, but he has power required to fit the Raiders' scheme.
McClain became necessary after Tony Bergstrom was placed on injured reserve with a foot injury. McClain will fit in behind left guard Lucas Nix and right guard Mike Brisiel.
Practice squad forming: Tight end Brian Leonhardt, guard Lamar Mady and receiver Greg Jenkins were added to the eight-man practice squad.
