The Cowboys are hanging onto a 10-7 halftime lead over the Saints, but they’re going to have to hang on the rest of the night without their best defensive player.
Linebacker Sean Lee has been ruled out with a concussion, ending his night after he took a hard shot to the helmet.
Lee has been excellent since rehabbing last year’s torn ACL and moving to the outside, and his kind of impact will be hard for the Cowboys to replace.
The Saints have their own issues as well, as left tackle Terron Amstead left the game, though no reason has been given for his absence. He was replaced by first-rounder Andrus Peat.
