Crows defender Sam Siggins has returned home to Tasmania due to personal reasons.
Siggins, who was taken at selection 62 in the 2012 National Draft, is unlikely to return this season.
The 21-year-old instigated discussions with the Club about his football future and subsequently will be delisted later this year.
Adelaide will continue to offer ongoing advice and support to assist in his future endeavours.
The Club will be making no further comment.
