The veteran running back played four snaps vs. the 49ers. He carried three times for four yards and caught one pass for three yards.
"I feel good. I came out yesterday and was just a little sore," McFadden said after Wednesday's morning walk-through. "But I definitely feel good and I'll be out there today."
McFadden played in all 16 games last season. It was the first time during his seven years in Oakland that he didn't miss a game because of injury. He said Wednesday that he's not looking to be cautious with his workload during the preseason or regular season. McFadden also said he "definitely" expects to play Saturday in Dallas' third preseason game.
