Mike Ditka, one of the most famous figures in NFL history, has died. He was 86.

His family announced his death Friday in a statement, Fox News reported. "It is with profound sadness that we announce the passing of our beloved husband, father, grandfather, and friend, Mike Ditka," the statement said. "While the world knew Mike as a Hall of Fame football player, legendary coach, and leader of the Chicago Bears' Super Bowl XX championship team, we knew him as the heart of our family."

Ditka was known as "Iron Mike" and "Da Coach." He was famous for his toughness, his temper and his mustache.

The Bears drafted him fifth overall in 1961, The Source reported. He changed the tight end position. Before Ditka, tight ends mostly blocked. He was also a strong receiver and a punishing runner after the catch. He later played for the Philadelphia Eagles and Dallas Cowboys and won two NFL championships as a player.

He became the first tight end elected to the Pro Football Hall of Fame, in 1988.

As a coach, Ditka led the 1985 Bears to one of the most dominant seasons in NFL history. That team went 15-1 and crushed the New England Patriots in Super Bowl XX. It featured stars like Walter Payton and a fearsome defense, and it even recorded a hit song, "The Super Bowl Shuffle."

Ditka later coached the New Orleans Saints and became a TV analyst. He also had restaurants in Chicago.

ESPN called him a legend whose fame went far beyond football. Fans in Chicago remain devoted to him decades after his coaching days ended.

What we don't: the cause of death or plans for a public memorial.
