San Diego, CA (SportsNetwork.com) - San Diego Chargers left tackle King Dunlap will not play against the Raiders on Sunday night because of a concussion.

Dunlap, who missed last Sunday's win over the Cowboys and didn't practice all week, was ruled out by the Chargers (2-2) on Friday.

Guard Chad Rinehart is doubtful with a toe injury and guards Jeromey Clary (clavicle), Rich Ohrnberger (groin), and cornerbacks Johnny Patrick (chest) and Shareece Wright (hamstring) are questionable.

Running back Ryan Mathews (hamstring), linebacker Manti Te'o (foot) and cornerback Derek Cox (knee) are probable.
