Raiders place DE Mario Edwards Jr. on IR with neck injury

ALAMEDA, Calif. (AP) The Oakland Raiders have placed rookie defensive end Mario Edwards Jr. on season-ending injured reserve with a neck injury.

Coach Jack Del Rio described the injury on Wednesday as ''significant.'' Del Rio says doctors are still deciding whether Edwards will need surgery. Del Rio did not go into detail about the injury or give any timetable for how long Edwards would be sidelined.

Edwards played just three snaps last Sunday against Green Bay before leaving with the injury. The second-round pick had 2 1/2 sacks as a rookie and was a key part of Oakland's defensive line.

The Raiders promoted linebacker John Lotulelei from the practice squad to take Edwards' spot on the 53-man roster.
