CHICAGO (CBS) — Chicago Bears legend Dick Butkus has died, the team confirmed Thursday.

“The Butkus family confirms that football and entertainment legend Dick Butkus died peacefully in his sleep overnight at home in Malibu, California.

“The Butkus family is gathering with Dick’s wife Helen. They appreciate your prayers and support.

“Additional information will be provided when it is available.”

Butkus, who played for the Bears from 1965 until 1973 and was an iconic representative of the team for generations, was 80 years old.

Butkus was born Dec. 9, 1942, to a Lithuanian American family in the Far South Side’s Fernwood neighborhood. He was the youngest of nine children.

Butkus’ website notes that he already knew he was going to be a professional football player by the time he was in fifth grade.

“I worked hard at becoming one, just like society says you should,” Butkus was quoted on its website. “It (society) said you had to be fierce. I was fierce. Tough. I was tough.”

Butkus became a star football player at Chicago Vocational High School, and at the University of Illinois – where he enrolled in 1961. By his junior year in 1963, he had already made 145 tackles and forced 10 fumbles, his website said.

He led the Fighting Illini to the Big Ten Championship that year – and they finished the season ranked third in the nation, his website said. The Illini beat Washington 17-7 in the Rose Bowl that year.

Butkus was unanimously named All-American in 1964 – playing both sides of the ball a center on offense and a linebacker on defense, his website said. He later had his University of Illinois jersey, No. 50, retired – and is only one of two players to have received such an honor there, his website said.

Butkus was drafted into the NFL by the Bears in 1965 – wearing jersey No. 51. He had 11 solo tackles in his first game, his website reported.

Butkus was a top contender for NFL Rookie of the Year that year, but was edged out by his Bears teammate and fellow first-round draft pick Gale Sayers, his website noted.

Butkus’ website said the 6-foot 3-inch, 245-pound powerhouse “terrorized opposing ball carriers and quarterbacks. His mauling style of tackling was worthy of a grizzly bear.”

In his nine-year NFL career, his website said, Butkus recovered 27 fumbles and had 22 interceptions.

Butkus was quoted on his website that his fierceness on the field was a major factor in his success.

“When I went out on the field to warm up, I would manufacture things to make me mad,” he was quoted. “If someone on the other team was laughing, I’d pretend he was laughing at me or the Bears. It always worked for me.”

Injuries began to take a toll on Butkus’ knees by 1970, but he pressed on for three more years – with 117 tackles and 68 assists, three fumble recoveries, and four pass interceptions in 1971, his website said.

When he retired in 1973, Butkus had been named first-team All-NFL for six years, and had been in eight consecutive Pro Bowls, his website said.

After retiring from the NFL, Butkus veered into acting – appearing in a well-known series of Miller Lite ads in which he played “a gentlemanly tennis player who cheerfully debates the beer’s merits with fellow ex-NFL defensive star Bubba Smith,” his website said.

He was also in the movies “Necessary Roughness” and “Any Given Sunday,” and appeared in the TV shows “My Two Dads” and “Hang Time,” his website said.

Just last year, Butkus took over the Bears Twitter feed – posting a couple of videos where he recalled his most memorable moments on the field.

He said his favorite game in which he ever played was a game against the San Francisco 49ers at Wrigley Field – which the Bears shared with the Cubs before they moved to Soldier Field in 1971.

“It’s the day that Gale Sayers scored six touchdowns and did it all different kind of ways – and you know, I was on all the kicking teams except the kickoff team at that point, but you know, we busted him on a punt return. I don’t know if he had a kickoff return or not. But he had six,” Butkus said.

Butkus added that Coach George Halas went on to take Sayers out of the game and replace him with Jon Arnett. If that had not happened, Butkus said, Sayers could have scored seven or more touchdowns.

That game was played on Dec. 12, 1965. Sayers noted it was a rainy day, much like the Bears’ home opener this year.

Future Head Coach Mike Ditka was also on the field as a player for that game – a contemporary Chicago Tribune account notes that he took out 49ers defensive lineman Roland Lakes to help clear the way for the fourth of Sayers’ six touchdowns.

The contemporary Tribune also noted that Johnny Morris took out a 49ers left linebacker to help clear the way in that same play. You may remember Morris as an iconic Chicago sports broadcaster, and specifically as CBS 2’s sports director from 1975 until 1992.

The Bears won that game 61-20.

A few years earlier in 2019, Butkus was honored with a 12-foot, 1,000-pound bronze statue outside Memorial Stadium at the University of Illinois.

The Hall of Famer was there to accept the unveiling. He was unfiltered, honest and in typical Dick Butkus fashion, there was absolutely no fluff.

“I deserve it?” asked Butkus. “Maybe the kids today would say it, but it’s a very humbling deal and you wonder why, man? I did what I was supposed to do and sh*t, I had fun knocking the sh*t out of people.”

Bears Chairman George H. McCaskey released a statement Thursday calling Butkus “the ultimate Bear.”

“He was Chicago’s icon. He exuded what our great city is about and, not coincidentally, what George Halas looked for in a player: toughness, smarts, instincts, passion, and leadership,” McCaskey wrote. “He refused to accept anything les than the best from himself, or from his teammates.”

The NFL also honored Butkus Thursday evening.
