EL PASO – Stadium lights beam down on a high school Friday night football game as the ball is snapped, shoulder pads clash and the crowd roars when the wide receiver dodges, turns around and reaches for the ball only to be blindsided by a crushing tackle that floors him with a concussion. Concussions are the most common injury athletes face and it is an injury that has lifelong medical consequences for young athletes. Sports-related concussions rank second in the number of brain injuries after motor vehicle accidents according to the Centers for Disease Control and Prevention. “We deal with some kind of concussion about two to three players a game,” said Casey Austin, a graduate assistant and athletic trainer at the University of Texas at El Paso. UTEP’s football team experiences some 24 concussions per season, he said, but “that’s not including practice concussions.” The number of concussions would be higher, he said, if practices are included.
