Two-time Washington Super Bowl champion Dave Butz has passed away. He was old.

The Washington Commanders were made aware of Butz's death on Friday. The cause of Butz's death was not known at the time.

After playing his first two years in the league with the St. LouisCardinals, Butz joined Washington and played 14 years in the league. He was one of the league's biggest players at the time and was a key member of the Washington defense that won two Super Bowl titles.

Butz was an All-Pro selection in 1983 and finished second in the voting for the AP Defensive Player of the Year when he started all 16 games for Washington. He was a member of the Pro Bowl that year.

A member of Washington's Ring of Fame and one of the 90 greatest players of all time, Butz retired after the 1988 season.

The team said it was sad over the death of a Washington legend.

Joe Theismann lost a friend. A man named Dave Butz. The three of us used to ride to games together. There is a giant. My friend, please rest in peace.

Butz had 64 sacks in the regular season. He was a free agent after the second season of his contract with the Cards. Washington had to give up two first-round picks and a second-round pick to sign him.

He was selected to the second team of the Pro Football Hall of Fame.

He is a member of the football team. He was elected to the college football hall of fame.
