Gordon (hip/knee) has been ruled out for Sunday's game against the Raiders.
With Gordon out this week, as expected, Kenneth Farrow is in line to head the Chargers' Week 15 backfield. On track to provide a change-of-pace option behind Farrow -- who logged 16 carries for 55 yards last Sunday in relief of Gordon -- is Ronnie Hillman, who was inactive in Week 14.
