With the Cowboys down 18 to Denver in the middle of the third quarter Sunday, Elliott, the defending NFL rushing champion, ran a route from the left slot. Quarterback Dak Prescott threw for the receiver just outside Elliott to the left, Dez Bryant, and the ball went through Bryant’s hands, and Denver’s Chris Harris intercepted it. At the time of the interception, Harris was about five yards away from Elliott. Elliott immediately stopped and put his hands on his hips and didn’t chase Harris.
