A second-round pick in 2010 out of Penn State, Lee was a two-time Pro Bowl selection (2015, 2016) and the unquestioned leader of the defense for most of his career.
“It’s been a complete honor,” Lee told ESPN. “I’ve been blessed to play for the incredible Jones family, with such great coaches and teammates that I love like brothers. I loved every minute playing and tried to pour my heart and soul into winning and helping my teammates at all costs.
“To say the injuries were frustrating would be an understatement, but the support I received through them all was humbling and the lessons I learned battling adversity will last a lifetime. There are always regrets, but I’m proud of what I was able to accomplish and I leave this game grateful.”
Injuries marked Lee’s time with the Cowboys, but when healthy he was one of the best linebackers in the NFL.
