Tretter gets long look at center

NASHVILLE, Tenn. — Though the rest of the Green Bay Packers' offensive line played only one series Saturday at Tennessee, starting center JC Tretter played the entire first half as the team tries to get him ready to be their new starter at a relatively new position for him.
Tretter played tackle in college but worked some at center last year when he came off the PUP list, and has been the starting center since the beginning of offseason work.
With Don Barclay out for the season because of a torn ACL sustained last week, Andrew Tiller was the right guard with the No. 2 line.
The rest of the No. 2 line consisted of Derek Sherrod at left tackle, Lane Taylor at left guard, and Aaron Adams at right tackle. Corey Linsley, a fifth-round draft pick, replaced Tretter at center to start the second half.
