In a statement released by the Chiefs, Polwart says he is grateful for the opportunities rugby has provided and the support he has received.
"It has been a difficult decision to make to leave the game I love. It has provided me with plenty of great friendships and some awesome experiences. I have had some ongoing issues with concussion, and while I am currently symptom-free, I chosen to hang up my boots and not to put myself at further risk."
