Jackson exited Thursday's practice due to a calf injury, Katherine Terrell of ESPN.com reports.
Jackson has started in both of the Saints' preseason contests and has accumulated five tackles (three solo) over that span. He's competing for a depth spot on New Orleans' linebacker corps behind starters Willie Gay, Demario Davis (hamstring) and Pete Werner (shoulder). Jackson operated mostly on special teams in 2023, finishing the season with 12 tackles (three solo) and a fumble recovery for a touchdown across 17 regular-season games.
