NAPA -- With depth issues on the interior of the defensive line, the Raiders announced the signing of defensive tackle Myles Wade on Wednesday.
Oakland has been without projected starting tackle Pat Sims since the start of training camp with an undisclosed injury. During Tuesday's practice, both Vance Walker and rookie Stacy McGee left with injuries. Walker is also projected to start.
Brandon Bair, who can play both end and tackle, has also been a spectator during the last two practices, as has nose tackle Johnny Jones.
If none of those players are able to return to practice Thursday after a player's day off Wednesday, that leaves the Raiders with second-year man Christo Bilukidi and undrafted rookie free agent Kurt Taufa'asau.
Wade, 6-foot-1 and 300 pounds out of Portland State, spent time with the Seattle Seahawks last season but did not see game action and has also previously been in camp with the Tampa Bay Buccaneers.
