As he tried to get back up, Jones appeared woozy. He started to walk gingerly back to the sideline when he stumbled. That’s when officials stopped Jones and called the trainers to the field. He was carted off the field.

Mike Glennon came on in relief of Jones and handed the ball off to Devontae Booker, who jumped over a pile for a touchdown. Booker was in for Saquon Barkley, who also left the game with an injury.
