The Raiders would not confirm the news, but Russell was limited in practice Thursday and did not participate Friday because of right knee tendinitis.
Oakland could also be without rookie running back Darren McFadden for a third straight game. McFadden has been sidelined with turf toe injuries in both feet, though it is his left foot that is causing the Raiders' first-round draft pick the most concern.
McFadden was fitted for a new pair of cleats in hopes of easing the pain in his foot, which still requires him to wear a protective boot when not practicing.
