The Arizona Cardinals have released Tyrann Mathieu.
The sides reportedly had been trying to restructure a contract that would have lasted through the 2021 season.
With his release, the former LSU standout will be free to sign with another team.
Mathieu played five seasons with the Cardinals and was named a first-team All-Pro after his third season, in 2015.
"I've never made a secret that Tyrann has always had a special place in my heart and always will," Cardinals general manager Steve Keim said in a release. "While we all understand this a part of the business, that certainly doesn't make it any easier.
