The Raiders placed linebacker Ben Heeney and tight end Cooper Helfet on the non-football injury list Tuesday.
Heeney ended last season on injured reserve after a Week Four ankle injury, but a non-football injury would indicate this is a different injury. Heeney did not fully participate in the team’s offseason program.
Heeney began last season as the starting middle linebacker, but he lost his job after two games and tore the deltoid ligament in his right ankle two weeks later.
Helfet signed with the Raiders’ practice squad last October. He played 24 games with the Seahawks in 2014-15, with 25 career receptions for 315 yards and two touchdowns.
The Raiders can activate either player at any time.
