Running backs Darren McFadden and Mike Goodson were not at practice Wednesday so it can’t look good for their chances to play Sunday. Defensive tackle Richard Seymour (hamstring) and starting safeties Tyvon Branch (neck) and Matt Giordano (concussion) were also out today. Tight end Brandon Myers was practicing so his concussion tests must be going well. It’s early yet, but the Raiders could be looking at starting Mike Mitchell at safety and moving Michael Huff back over from cornerback. The only defensive back on the practice squad is second-year cornerback Chimdi Chekwa. Source: San Francisco Chronicle
