Thornton (hamstring) has been ruled out for Sunday's game against the Rams, Sam Warren of The Athletic reports.
Thornton logged a trio of full practices during Week 7 prep, but head coach Klint Kubiak told reporters Friday that the second-year wide receiver will remain on injured reserve for at least one more week. Thornton's 21-day practice window opened Oct. 7, and he would be forced to miss the rest of the 2026 season if the Raiders do not activate him from IR by Wednesday.
