The Green Bay Packers signed offensive guard T.J. Lang to a four-year contract extension on Tuesday.

The four-year pro out of Eastern Michigan started all 16 games last season, 15 of them at his customary left guard position. He has started games at three different positions on the offensive line over 44 regular-season games with 19 starts in his NFL career.

Lang was drafted by the Packers in the fourth round of the 2009 NFL Draft and played in all 16 games (three starts) as a rookie.
