Sean Lee’s injury history grew more on Sunday night.
The Cowboys’ weak side linebacker was diagnosed with a concussion from a collision between him and Saints tight end Benjamin Watson in the first quarter, and didn’t return.
Lee, 29, must pass concussion protocol before returning to practice and game action. There’s a chance he could miss next Sunday’s game against the New England Patriots. The Cowboys then have a bye week.
Lee is among the most talented players on the Cowboys, but staying on the field has been an issue his entire career. He has missed 34 regular-season games over six seasons.

Lee missed all of last season after tearing his anterior cruciate ligament in the offseason. He has also missed games with injuries ranging from hamstring to a dislocated wrist to toe surgery.
Lee was injured in 2013 when the Cowboys last visited the Saints, straining his hamstring that sidelined him for five games.
Rookie Damien Wilson came into the game to take Lee’s spot.
Lee’s injury was certainly a blow to the defense. Lee worked his way back into being the difference-making player he had been in the past, and was excelling on the weak side in Rod Marinelli’s Tampa 2 scheme.
Lee set a ‘production points’ record for his Week 2 performance against the Eagles, earning NFC defensive player of the week honors. He had a team-leading 14 tackles, including two tackles for loss, as well as an interception.
In other injury news, Cowboys reserve tight end James Hanna played through an ankle injury that limited him in the first half. Running back Lance Dunbar injured his knee on the opening kickoff return of the second half, as well.
