A former walk-on at Auburn who went on to greatness in the NFL, Kevin Greene has died. He was 58.

Greene walked on in 1983, and played special teams on Auburn’s SEC Championship team. In 1984, Greene led the SEC in sacks, despite not starting until the final four games of the season.

Greene was drafted in the fifth round by the Los Angeles Rams in 1985, and played 15 seasons in the NFL. His 160 sacks rank third in NFL history, behind Bruce Smith and Reggie White.

Greene was a member of the class of 2016 in the Pro Football Hall of Fame, and his 15-season NFL career was highlighted by 160 sacks, which stands as the third-highest total in league lore.

“The entire Pro Football Hall of Fame family mourns the passing of Kevin Greene,” Hall of Fame President and CEO David Baker said in a statement, per NFL.com. “I regarded him as a personal friend and a true Hall of Famer in every sense. He possessed the most incredible can-do attitude of anyone I ever met. He was a great player, but more than that, he was a great man. Our thoughts and prayers are with Kevin’s wife, Tara, 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 Kevin’s memory.”

Greene spent eight seasons in the Rams organizations, and also played for the Pittsburgh Steelers and Carolina Panthers — three seasons apiece — and a season with the San Francisco 49ers.
