"Jackson tried as hard as he could to convince the trainers he was okay and could go back in the game. They made him put all his body weight on his right leg and lift up with his toe. He went through a series of change of direction drills on the sidelines. At the very least, he made it look good. However, as soon as he was done with those change of direction drills, a likely realization of pain came over him. He yelled out and clapped out of frustration as his eyes began to well up, made a beeline for the bench and put a towel over his head. He knew his day was over, and likely feared the worst."
