It's a move reporters close to the team expected all along, with Hali turning 35 in December and set to save the Chiefs nearly $7.7 million with his departure.
"I'm grateful I had the privilege of working with Tamba and getting to know him on a personal level," coach Andy Reid said in a statement. "His love for the game is incredible, and he's passed on that passion and his knowledge to a lot of our young players. I can see him being a coach one of these days. He's built a tremendous legacy here in Kansas City, and we wish him the best as he moves forward."
The veteran pass-rusher battled knee issues in 2017 and largely operated as a nonfactor, appearing in just six games and failing to tally a sack. Not his best season, but Hali -- the team's first-round pick in 2006 -- leaves Kansas City ranked second in club history behind Derrick Thomas with 89.5 career takedowns.
It's entirely possible Hali finds another opportunity at a reduced rate -- pass-rushers are tough to pinpoint -- but the Chiefs are finally moving on from one of their most celebrated stars of the 2000s.
