Darren McFadden working out again

Raiders HC Dennis Allen revealed that RB Darren McFadden (foot) is working out again.  "His foot is better," Allen said.  "He was back in town, working out last week, and we got a good evaluation on him. Darren will be ready to go whenever we get ready to kick off the season."  Run DMC missed the final 9 games of last season with what turned out to be a Lisfranc injury.  Oakland has been tight-lipped about his status since he went down in October.
