Greene was waived by the Chiefs on Tuesday.
Greene's last regular-season action came in 2014 with the Bears, when he played in 10 games and posted 16 tackles. Despite a few short stints with both the Buccaneers and Bears, Greene has since fallen out of the league, and the fact that he's being waived this early in the offseason doesn't bode well for his chances of making a final roster elsewhere.
