When Indianapolis Colts quarterback Jacoby Brissett groggily pulled himself up after a hit to the head Sunday against the Pittsburgh Steelers and went to the sideline, he was directed to a blue pop-up tent.
That tent is new for the NFL this season, and every team is required to have one. Doctors use it to conduct quick concussion tests in private, away from fans, game play, cameras, lights and other distractions.
