Jackson (groin) has been downgraded from doubtful to out for Sunday's game against the Saints, Joe Person of The Athletic reports.
Jackson's 21-day practice window opened Wednesday, and he drew the doubtful tag for Sunday's game after logging a trio of limited sessions. He's not quite ready to return from a groin injury that landed him on IR in late September, and his next opportunity to suit up is Week 11 against the Ravens on Sunday, Nov. 22.
