Four-time Super Bowl champion Mike Wagner, a ballhawk at safety and a member of the Pittsburgh Steelers Hall of Honor, has died. He was 76.

The Steelers, for whom Wagner played all 10 of his NFL seasons, announced his death Wednesday night.

“We are deeply saddened by the passing of Mike Wagner, a tremendous player and an integral part of some of the most successful teams in Pittsburgh Steelers history,” Steelers president Art Rooney II said in a statement.

“Mike played a key role on our championship teams of the 1970s. As a member of four Super Bowl-winning teams, his toughness and consistence were paramount to our secondary. His contributions on the field were significant, but it was also his steady presence and team-first mentality that truly defined him.

“On behalf of the entire Pittsburgh Steelers organization, we extend our heartfelt condolences to Mike’s family. He will always be remembered as a champion, a great teammate and a proud member of the Steelers family.”

One of the top safeties of his era, Wagner had a knack for making big plays in the biggest games.

As a key part of the famed “Steel Curtain” defense, Wagner intercepted the Vikings’ Fran Tarkenton in Super Bowl IX and picked off the Cowboys’ Roger Staubach in Super Bowl X. Both were fourth-quarter takeaways from future hall of fame quarterbacks — late picks that helped the Steelers hoist the Lombardi Trophy each time.

A two-time Pro Bowl selection, Wagner was inducted into the Steelers Hall of Honor in 2020.

The 6-foot-1, 210-pound defensive back had 36 career interceptions, not including his five in the postseason.

In 1973, Wagner tied for the NFL lead with eight interceptions. He still ranks sixth among Steelers in career interceptions.

An 11th-round draft pick in 1971 out of Western Illinois, Wagner became a starter right away. He started 116 of 119 regular-season games over his career.

He also started in three Super Bowl victories, with a hip injury sidelining him for the second half of the 1979 season.

Wagner earned consecutive Pro Bowl nods in 1975 and ’76. He also earned a spot on the All-Pro second team in 1976.

He remained in Western Pennsylvania as a businessman after his retirement.
