EL SEGUNDO, Calif. (AP) — Los Angeles Chargers safety Derwin James has been suspended one game without pay by the NFL for repeated violations of rules intended to protect players’ health and safety. James has five unnecessary roughness penalties in his last 18 games, the most in the league by a defensive player. All five have involved blows to the head of an opponent with his shoulder or helmet. Jon Runyan, the league’s vice president of football operations, pointed to James’ targeting of Steelers tight end Pat Freiermuth during the third quarter of Sunday’s game as the last straw.
