Green Bay Packers safety Morgan Burnett was unable to practice Wednesday for an unknown reason, but he was the only member of the team's 53-man roster who was held out.

The list of players participating on the field included receiver Randall Cobb, who practiced for the first time since spraining his right shoulder in the team's third preseason game against the Philadelphia Eagles on Aug. 29. It's a good sign Cobb will be on the field when the Packers travel to Chicago for their 2015 opener on Sunday against the Bears.

Cobb, the Packers' top receiving threat following Jordy Nelson's season-ending ACL injury, had previously expected to play against the Bears but did not know how much he'd be able to practice this week.

Cobb wasn't the only player who returned to practice. Joining him were right guard T.J. Lang (concussion), defensive back Micah Hyde (neck), rookie receiver Ty Montgomery (hamstring), and cornerback Demetri Goodson (knee). Inside linebacker Nate Palmer and running back Alonzo Harris practiced without clubs on their hands for the first time since being injured during training camp.

Lang's return was especially important for an offensive line battered with injuries during the preseason. He hadn't practiced since exiting early in the Packers' second preseason game at the Pittsburgh Steelers on Aug. 23. With Lang back, the Packers have their entire starting offensive line intact. Left tackle David Bakhtiari (knee) and left guard Josh Sitton (ankle) returned to practice last week after missing multiple preseason games.
