U.S. football player.
He played for the University of Illinois before joining the Chicago Bears (1965–73). He became known for his aggression and toughness on the field as much as for his playmaking ability. His career was shortened by injuries; after retirement he became active in television and sports promotion. Butkus is considered among the best middle linebackers of all time.
