Minutes after the decision became public, Winston took to Twitter to share his feelings.
"Just wanted to confirm that I have been released," he wrote. "Even though it was an incredibly tough year on and off the field last year, I wouldn't trade the relationships I made in KC and the overall experience I had for anything. It was an honor to be a Chief and I wish them nothing but the best in the future. ... On to the next adventure!"
Winston's tenure with the Chiefs ends less than one year after he signed a four-year, $22 million contract as a free agent. The move saves $3.5 million in cap space. Winston made headlines in October when he criticized Chiefs fans who cheered when quarterback Matt Cassel went to the locker room with a head injury.
