T.J. Lang is hoping to fully participate in practice in a few days, perhaps as soon as after the team's day off Tuesday.
The Packers' starting right guard has been taking part only in select individual drills because of a sore shoulder that cropped up while working out between the end of offseason practices in mid-June and the start of training camp.
"It was nothing I did in particular that hurt it," he said. "It's something that's built on me the last couple years and caught up to me. Nothing serious at all. Something similar to (tendinitis). Have to calm it down a little bit before I get back out there."
The Packers open camp with three days of practice, followed by a day off Tuesday and then four straight days of practice, including Family Night on Saturday at Lambeau Field.
Don Barclay has been taking most of the snaps at right guard with the first-team offense in Lang's absence.
New injuries: Jamari Lattimore (stomach illness).
Still out: OLB Nick Perry (knee, foot), WR Jeff Janis (illness), OLB/DL Mike Neal (core/abdomen), DL Letroy Guion (shoulder), DL Jerel Worthy (lower back).
