His death was confirmed by the teams Friday, with no details given. Nasir Adderley, a safety for the Los Angeles Chargers, tweeted that his cousin was a “unique soul who has had such an incredible influence on my life.”

Herb Adderley played in four of the first six Super Bowls and won five NFL championships with Green Bay and one with Dallas during his 12-year career.

But he was always a Packer at heart.

“I’m the only man with a Dallas Cowboys Super Bowl ring who doesn’t wear it. I’m a Green Bay Packer,” Adderley said in the book “Distant Replay,” a memoir by former Packers teammate Jerry Kramer.

Along with former teammates Fuzzy Thurston and Forrest Gregg, Adderley is one of four players in pro football history to play on six championship teams.

Bart Starr, the Hall of Fame quarterback and a former Packers teammate, once called Adderley the “greatest cornerback to ever play the game.”
