Dave Edwards, a linebacker who helped lead the Dallas Cowboys to three Super Bowls and was part of the team’s so-called Doomsday Defense, died on Monday at his home in Lake Whitney, Tex., about 80 miles southwest of Dallas. He was 76.
His death was confirmed by his brother, Timothy. He had been scheduled to have surgery on Thursday for a heart arrhythmia that was recently discovered, his brother said.
Dave Edwards played for the Cowboys from 1963 through the 1975 season. Known for his speed and aggressiveness, he was considered a key component of the team’s defense.
