The Packers have given guard T.J. Lang a new, four year contract extension. Financial terms were not disclosed. Lang is entering his second season as the starter at left guard. T.J. has also started games at both tackle positions in his career. He is a fourth year pro and a former fourth round draft pick out of Eastern Michigan. It's the second contract extension offered by the Packers this summer. Punter Tim Masthay signed a new deal 10 days ago.
