Wide receiver DJ Chark has been ruled out of the Chargers' season opener against the Raiders due to a lingering hip injury that has kept him out of practice all week. This leaves the Chargers with Joshua Palmer, Ladd McConkey, and Quentin Johnston as the leading wideouts for the game. Additionally, cornerback Asante Samuel Jr. is listed as questionable due to a shoulder injury. On a positive note, quarterback Justin Herbert fully participated in practice and has no injury designation. Chark, who signed a one-year deal with the Chargers this offseason, will aim for a potential return on September 15 against the Panthers.
