Darren McFadden leads injured Raiders

The Oakland Raiders will be severely limited by injuries for Sunday's game against the San Diego Chargers.

Running backs Darren McFadden and Michael Bennett and guard Robert Gallery haven been ruled out because of hamstring problems. Also, linebacker Quentin Groves and cornerback Walter McFadden are questionable with hamstring injuries.

Wide receiver Chaz Schilens (knee), linebacker Travis Goethel (back), linebacker Thomas Howard (knee) and defensive tackle John Henderson (foot) have also been scratched.

Linebacker Rolando McClain returns to practice on Friday after missing two days because of a death in the family.
