TJ Lang has agreed to a 4-year extension with the Packers.— Adam Schefter (@AdamSchefter) August 14, 2012
Lang spent his three previous seasons with Green Bay after being drafted out of Eastern Michigan in 2009. After three starts in 28 games over his first two seasons, he started all 16 regular-season games and the playoff game for the Packers last season. Fifteen of those 16 starts came at left guard.
He was one of two Packers offensive linemen to start every regular-season game last season. He has also started games at left tackle and right tackle in his career. He started at both tackle spots as a rookie in 2009.
