Raiders running back Darren McFadden is officially listed as doubtful on the team’s injury report. That might be a shade optimistic. While he missed a week’s practice with a hamstring injury suffered in the Washington loss that’s not what shrouds his playing status for Sunday against San Diego in pessimism. It’s what he said in his only interview of the week. “Hamstrings are one of those things you want to be careful with” McFadden said after Friday’s practice. “I’d rather miss one or two games than to come back and pop it and miss four or five.” One or two games? Two games would put him out against the Chargers and Chiefs heading into the bye week. “I think it’s going to help me out a whole lot” McFadden said. “But at the same time we’re just taking it day-to-day right now.” There’s no guarantee McFadden will miss two games or even one for that matter. The Raiders maintain that they’ll continue to monitor him until kickoff that he doesn’t need practice reps to play.
