Angus MacDonald says he was "immensely proud" to represent Hull City after his exit from the club was confirmed.
The 27-year-old has departed the KCOM Stadium after his contract expired.
He joined City in January 2018 but was restricted to just 21 appearances.
His journey back to playing following his battle with cancer was an inspiration to all.
He made an emotional return to the pitch earlier this year after 672 days without playing a competitive match following recovery from a blood clot and overcoming bowel cancer.
Following confirmation of his departure from City, MacDonald posted a poignant message on social media.
He said: "My time at Hull City has come to an end and it's been one crazy rollercoaster of emotions throughout my time at the club!
"I never got to pull on the shirt as much as I would have liked, but when I did I was immensely proud to represent the team and the city."
The lengthy message also thanked colleagues, staff and supporters.
MacDonald, who is interesting several Championship teams, signed off by saying: "I really hope to see the club bounce back soon, you deserve it.
"If you see me out and about, please don't hesitate to say hello!"
