Buckner, 46, who coached the Cardinals defensive line the past five seasons, guided a unit that helped Arizona lead the league in sacks with 48 in 2016. He replaces Jay Hayes, who was fired Feb. 9 after the Bucs finished last in the NFL with 22 sacks in 2017.
Buckner played 12 seasons in the NFL with the Steelers, Bengals, 49ers and Panthers. In 2001, he joined Julius Peppers, Mike Rucker and Kris Jenkins to form what many believed was one of the most dominating defensive fronts in football which led the Panthers to Super Bowl XXXVIII against the New England Patriots.
