Wide receiver Jacoby Ford has been officially ruled out of Monday night's game against San Diego with a sprained left foot.
Ford hasn't played or practiced since being injured Aug. 17 during a preseason game at Arizona. He missed six games last season with a similar injury.
The Raiders' injury report listed four players as questionable: WR Denarius Moore (hamstring), DT Richard Seymour (knee), G Cooper Carlisle (back) and WR Juron Criner (ankle).
Moore practiced Thursday for the first time since Aug. 4 and practiced again Friday. He's expected to practice again Saturday evening at the O.co Coliseum. Barring a setback, he appears to be on track to play Monday night.
Four players are listed as probable: K Sebastian Janikowski (left groin), TE Brandon Myers (shoulder), C/G Stefen Wisniewski (calf) and TE David Ausberry (shoulder).
