Gale Eugene Sayers was an American professional football player who was both a halfback and return specialist in the National Football League (NFL). In a relatively brief but highly productive NFL career, Sayers spent seven seasons with the Chicago Bears from 1965 to 1971. He was known for his elusiveness and agility and was regarded by his peers as one of the most difficult players to tackle. Nicknamed the "Kansas Comet", Sayers played college football for the Kansas Jayhawks football team of the University of Kansas. Sayers was inducted into the Pro Football Hall of Fame in 1977 at age 34 and remains the youngest person to have received the honor.

He was an NFL champion with the 1963 Bears, and is a three-time Super Bowl champion. He is known by the nickname "Iron Mike", which he has said comes from his being born and raised in a steel town in Pennsylvania.
