"Jason is everything you look for in a left tackle," Eagles general manager Howie Roseman said. "The unique blend of size, speed and athleticism that Jason possesses is something that everyone wants in an offensive lineman. However, what really makes him unique is his desire to improve day in and day out despite the fact that he's played at an elite level for so many years. We are truly rewarding Jason's excellence, as he's a guy who has made six Pro Bowl appearances and has been selected an All-Pro five times. We're excited to be able to keep him in Philadelphia for years to come."
