KANSAS CITY, Mo. (AP) - — The Kansas City Chiefs have officially placed running back Jamaal Charles on season-ending injured reserve and promoted wide receiver Jeremy Horne from the practice squad.
Charles tore the ACL in his left knee in the first quarter of Sunday's 48-3 loss to the Detroit Lions. He is the third Chiefs player to sustain the injury in recent weeks. Tight end Tony Moeaki went down in their preseason finale and Eric Berry in a season-opening loss to Buffalo.
Coach Todd Haley said Monday that he expected Charles to go on IR and the team made the move official Wednesday. The Chiefs also announced they signed offensive lineman Lucas Patterson to fill Horne's place on the practice squad.
Horne played in three games for Kansas City last season.
