Former Michigan State star Herb Adderley passed away on Friday at the age of 81, according to the Pro Football Hall of Fame:

Adderley played as a running back at Michigan State prior to switching over to cornerback in the pros. Adderley was an All-Big Ten selection at Michigan State and was chosen with the 12th overall pick by the Green Bay Packers in the 1961 NFL Draft.

The Pro Football Hall of Fame member went on to capture six pro championships between the Packers and Dallas Cowboys. Adderley was selected for the NFL’s 1960’s All-Decade Team.

Adderley, regarded by many as the game’s greatest cornerback, amassed 48 interceptions and 7 pick-sixes during his NFL career.

“The entire Pro Football Hall of Fame family mourns the passing of Herb Adderley. He was a great player and an even greater man. Herb left an indelible mark on the Game and was respected tremendously by players and personnel across the league,” Hall of Fame President & CEO David Baker said. “Our thoughts and prayers are with Herb’s wife, Brenda, and their entire family. We will forever keep his legacy alive to serve as inspiration for future generations. The Hall of Fame flag will be flown at half-staff in Herb’s memory.”
