Running back Darren McFadden, though, was not on the practice field, fueling speculation that he aggravated his troubled right hamstring. Neither was running back Jeremy Stewart, who suffered knee and ankle injuries on Thanksgiving at the Dallas Cowboys.
And while Rashad Jennings was back after suffering a concussion against the Cowboys, converted cornerback/gunner Taiwan Jones was getting reps at running back.
Also, receiver Denarius Moore, who has missed the past two games with a shoulder injury, was not practicing. Right guard Mike Brisiel, who injured a knee on the Raiders’ first play at Dallas, was an observer.
