The Los Angeles Chargers placed running back Gus Edwards and cornerback Asante Samuel Jr. on injured reserve. They will miss at least the next four games.
Samuel's designation came as a significant surprise. He practiced all week except Friday, when he was ruled out with a shoulder injury. Coach Jim Harbaugh said Friday that the injury didn't happen at practice.
Samuel suffered a shoulder injury in practice ahead of the Chargers' Week 1 game against the Las Vegas Raiders and was questionable for that game but played and hadn't missed any time since.
