"We are saddened to learn of the passing of Bill Leavy, a longtime NFL referee and a current member of the league’s officiating staff," NFL's senior vice president of officiating, Walt Anderson, said in a statement. "Bill was an outstanding official and an even better man. Always kind and thoughtful, Bill was instrumental in mentoring countless young officials throughout his career. His recognition as an Art McNally Award winner highlights that selfless dedication to officiating. His integrity earned him respect at every step of his football journey and the entire officiating community mourns his loss."
