After 11 seasons with the Cowboys, linebacker Sean Lee tells ESPN he is retiring. Injuries marked his career, but he was a two-time Pro Bowler and was a first-team All-Pro selection in 2016 and the unquestioned leader of the defense. Lee, 34, owns five of the top-seven tackle games in team history, including a record 22 vs. the Giants in 2016. He also had 14 career interceptions, returning two for touchdowns, five fumble recoveries, two forced fumbles, 59 tackles for loss and four sacks.
