The Chiefs are releasing veteran wide receiver Josh Gordon, a source confirmed to ESPN on Tuesday.

Gordon said a public farewell to the Chiefs and their fans in a pair of tweets Tuesday, appearing to confirm his exit.

"Appreciate all the @Chiefs kingdom has done for me and my family this past year. Thanks for the opportunity and the many memories," he tweeted and then added: "Excited to see where the next part of my football journey takes me #itsabusiness #dreamchasing."

NFL Network first reported that Gordon was being released.

Gordon, 31, led the NFL with 1,646 receiving yards in 2013, when he played for the Cleveland Browns. Since then, Gordon has been suspended by the NFL six times, five for some form of substance abuse, according to ESPN Stats & Information .
