Packers list JC Tretter as backup at 2 spots

GREEN BAY, Wis. -- JC Tretter is back, and he's back at one of his old positions.

The Green Bay Packers listed the second-year pro as the backup at left tackle, the position he played in college at Cornell. He's also listed as the No. 2 center on their latest depth chart released on Tuesday.

Tretter was activated from the injured reserve/designated to return list on Monday, replacing tackle Derek Sherrod, the former first-round pick who was released in a somewhat surprising move.

Tretter spent the entire offseason as the starting center and was on track to be the opening-day starter until he sustained a knee injury during the third preseason game. He has not played since. In his absence, rookie Corey Linsley has played so well at center that the Packers don't plan to go back to Tretter.

Sherrod had been the backup at both tackle spots, but the Packers listed starting right guard T.J. Lang as the backup at right tackle.

However, Lang's status for Sunday's game against the Chicago Bears is unclear after he sustained a sprained left ankle in the Oct. 26 loss at the New Orleans Saints. Lane Taylor finished the game in Lang's place and is listed as the backup. However, it's possible the Packers would use Tretter in that spot if Lang can't play.

Sherrod cleared waivers on Tuesday, making him a free agent.
