Raiders S Gibson placed on injured reserve

Raiders safety Derrick Gibson was placed on injured reserve, five days after dislocating his left wrist.

Gibson was injured early in Oakland's 38-17 victory over Buffalo. The fifth-year pro from Florida State underwent surgery to place pins in his wrist.
Oakland signed linebacker Isaiah Ekejiuba from the practice squad to take Gibson's roster spot. Jarrod Cooper, Stanford Routt and Chris Carr all will help fill Gibson's absence on Sunday at Tennessee.

Gibson's promising career repeatedly has been derailed by injuries. He missed all of the 2004 season on injured reserve after he dislocated his shoulder in the final preseason game.

The Raiders also lost star cornerback Charles Woodson in the win over Buffalo. Woodson, a four-time Pro Bowl player, is expected to be out six to eight weeks with a broken right leg.
