The Suns delisted Garlett after he last week requested to be released from his contract in order to allow him to return home to Western Australia to deal with a family matter.
In a a blow for Garlett, he will be unable to play for another AFL club for the next two years, after he signed a two-year contract extension in August this year.
He played 17 games in two seasons after being recruited with pick No. 15 in the 2014 National Draft.
“Our player development team and wider support network has been working with Jarrod for some time to assist him in adjusting into life away from his family,” General Manager of Football Operations, Marcus Ashcroft said.
“In the midst of this, a significant change in circumstances with his family back in Western Australia led to Jarrod making the decision it was in his, and his family’s best interests to be released from his contract.”
“We continue to work with Jarrod and his management to ensure Jarrod’s transition into life away from the AFL is as smooth as possible and we wish him and his family all the very best in the future.”
