Jones (ankle) was waived/injured by the Rams on Tuesday, Stu Jackson of the Rams' official site reports.
The Rams backfield has been beset by injuries this summer, with Cam Akers (Achilles) and Raymond Calais (foot) already on IR and Jones set to join them, assuming he clears waivers. If he does, Jones will have a chance to return at some point this season once his left ankle is healthy. For the time being, however, Los Angeles will rely on Darrell Henderson (thumb), Sony Michel and Jake Funk at running back.
