the San Francisco 49ers with an injured right hamstring.

This is the second straight game McFadden has missed with the

The Raiders are also without their starting quarterback. Bruce
Gradkowski is slowed by a right shoulder injury and is listed as
the third quarterback. Jason Campbell will get the start and Kyle
Boller is the No. 2 quarterback.

Among the inactives for the 49ers are former Raiders offensive
lineman Barry Sims and tight end Delanie Walker, who has an injured
ankle.
