Dallas Cowboys linebacker Sean Lee left Sunday night's game with the New Orleans Saints with a brain injury, according to Michele Tafoya on the NBC broadcast.
Sean Lee ruled out for Sunday night’s game with concussion
Dallas Cowboys linebacker had at least two previous brain injuries.


Tafoya announced early in the second quarter that Lee had returned to the Cowboys locker room to be checked for a concussion, then updated viewers just before halftime to announce he was out for the rest of the game. Lee has suffered at least two previous brain injuries -- one in 2010 and another in 2013.
Lee missed all of the 2014 season with the third major knee injury of his career -- he suffered the first two at Penn State -- but returned strongly this season. He was named the NFC Defensive Player of the Week after recording 14 tackles and an interception in a 20-10 win over the Philadelphia Eagles.
He has been plagued by injuries throughout his career, having averaged only 9.2 games in his first five NFL seasons. Along with his knee and head injuries, he has sustained foot and wrist problems.
The Cowboys trailed 7-3 when Lee left the game, but scored shortly afterward to take a 10-7 lead.
