Packers running back Marshawn Lloyd came down with appendicitis last week after the club opened his 21-day practice window.
Green Bay has now made a roster move with him, activating him off of injured reserve.
That does not mean Lloyd, a rookie third-round pick, is going to be ready to play soon. He could be placed on the non-football injury list to recover from his appendectomy.
Head coach Matt LaFleur has not given a timetable for Lloyd's potential return.
Lloyd has appeared in one game for Green Bay this year, recording 15 yards on six carries and a 3-yard catch in 10 offensive snaps.
