Packers general manager Ted Thompson said Monday that Rivera was the consummate professional who was a great model for his teammates.
Rivera spent nine seasons from 1996 to 2004 in Green Bay.
During his tenure with the team, Rivera played in 99 consecutive regular season games and was selected to three Pro Bowls.
Rivera finished his career after two years in Dallas and was released in June 2007.
Rivera says it's an honor and a privilege to retire with the Packers.
