His cause of death has not been confirmed at this time.
Greene was inducted by the Pro Football Hall of Fame in 2016. He played on multiple teams in his 15 seasons at the NFL, including Pittsburgh, the Los Angeles Rams, the Carolina Panthers and the San Francisco 49ers.
Greene also made coaching stops as a linebacker coach for the Green Bay Packers and New York Jets. He had 160 total sacks in his career, which is currently the third-highest in the league behind Bruce Smith (200) and Reggie White (198).
“I wasn’t the biggest (and) I wasn’t fastest,” Greene once said. “But as long as you have a motor, you have heart…that will overcome any physical limitations.”
Greene also had 23 forced fumbles and five interceptions.
“The entire Pro Football Hall of Fame family mourns the passing of Kevin Greene. 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.”David Baker, Hall of Fame President and CEO
Greene played for the Steelers from 1993-1995. The Hall of Fame flag will be flown at half-staff in honor of his memory.
Members of the Jets made their condolences as well.
“To the coach that believed in me and gave me an opportunity as a Undrafted kid as he called “Out of nowhere coconut head” to make my dreams comes true was a blessing! I will always remember your saying “there’s no substitute on kicking a man a(asterisk)(asterisk). RIP KG” tweeted Jets linebacker Frankie Luvu.
