The Raiders went with four defensive tackles on their initial 53-man roster.
Run stopper Justin Ellis wasn’t one of them. The veteran was placed on season-ending injured reserve with a knee injury.
Last week, head coach Jon Gruden said Ellis might be ready for the regular season opener. It’s uncertain if there was an injury setback, but he’s no longer eligible to play for the Raiders on Sept. 9 against Denver.
It’s possible the Raiders reach an injury settlement with him if the ailment isn’t season ending and Ellis wants to get back in the game in 2019, though that’s ultimately uncertain.
