IRVING, Texas — Jethro Pugh played alongside Hall of Famers Bob Lilly and Randy White in a long career as a defensive tackle for the Dallas Cowboys, which may explain why he was among the most unsung Super Bowl winners in the franchise’s storied history.

Pugh, who played in the first four Super Bowls for Dallas and was part of a “Doomsday Defense” that won two of them, died Wednesday. He was 70.

The team said Pugh died of natural causes four days before the Cowboys were to play their first postseason game in Green Bay since the famous Ice Bowl in 1967. Pugh was blocked on Bart Starr’s quarterback sneak for the game-winning touchdown in Dallas’ 21-17 loss in the Ice Bowl that sent the Packers to the second Super Bowl.

“He was loved and appreciated by his teammates and Cowboys fans for decades, and his spirit will be felt when our team travels to Green Bay this weekend,” owner Jerry Jones said.
