He had not practiced or played since until Thursday, when he was back in full pads and going through drills.
The Packers did not rule him out yet this week like they have each of the first four weeks of the season. Hayward originally pulled his hamstring during a pre-training camp workout. He returned midway through camp but was reinjured in the Aug. 23 preseason game against the Seattle Seahawks.
Defensive tackle Ryan Pickett appeared to drop out of practice during the portion that was open to reporters. His status will be updated after practice.
Not practicing were: cornerback Jarrett Bush (hamstring), running back James Starks (knee), linebacker Clay Matthews (thumb), linebacker Andy Mulumba (ankle), linebacker Brad Jones (hamstring) and offensive lineman Greg Van Roten (foot).
The Packers were so thin at linebacker that practice squad tight end Jake Stoneburner took reps on defense with the scout team.
The latest addition to the practice squad, offensive lineman Garth Gerhart, joined the Packers in time for practice. Gerhart was with the Packers during the preseason. He replaced receiver/kick returner Reggie Dunn, who was released after just 10 days.
