“I would like to thank the Sydney Swans Football Club for the opportunities they have given me over the past eight years,” Johnson said.
“I have made life-long friends and lived out my childhood dream of playing AFL, including the premiership in 2012.
“Although it has been a very difficult last six years I will be forever grateful that the Club stuck by me and gave me every opportunity to get back and play at the highest level.
“While I am disappointed with the decision the Club has made, my passion still remains to play football at the highest level.”
