LOS ANGELES — Los Angeles Rams running back Cam Akers is out indefinitely after tearing his Achilles tendon in an offseason training session.

The Rams confirmed the injury Tuesday, one week before veterans report to training camp.

Akers was expected to be the Rams’ starter in the backfield after coming on late in his outstanding rookie season. Akers had 272 yards from scrimmage in the Rams’ two playoff games, capping his rookie year with some of his best play.
