Packers practice sans T.J. Lang, Josh Sitton

GREEN BAY, Wis. -- The bye week was good to the Green Bay Packers' secondary but apparently not good enough to their offense line.

They were without both starting guards, T.J. Lang and Josh Sitton, when they practiced on Wednesday in preparation for Sunday night's game against the Chicago Bears at Lambeau Field.

Lang, the starting right guard, dropped out of the Oct. 26 loss at the New Orleans Saints after he sprained his left ankle on the first series. However, Sitton played the entire game at his left guard spot and was not mentioned among the game's injured players.

Although there were no team periods conducted during the portion of practice that was open to reporters, the Packers likely would use Lane Taylor and recently activated JC Tretter at the guard spots if both Lang and Sitton were out. Garth Gerhart also would be an option.

As expected, quarterback Aaron Rodgers, who sustained a hamstring injury against the Saints, was on the field and appeared to be moving without any trouble. He said Tuesday on his ESPN Milwaukee radio show that his hamstring was "fine."

The secondary was back at full strength with the return of safety Morgan Burnett and cornerback Sam Shields. Burnett missed the game against the Saints because of a calf injury, while Shields has not played since his Week 6 knee injury.

Defensive end Datone Jones, who has not played since his Week 5 ankle injury, also returned to practice.

The full injury report will be available following practice.
