The AFL career of Sam Butler is in doubt after the West Coast premiership defender underwent season-ending shoulder surgery.
Butler, who hasn't played since round 15, has had surgery to address an ongoing tendon issue in his right shoulder.
The 31-year-old is out of contract at the end of the AFL season, and is unlikely to survive West Coast's off-season cleanout.
Matt Priddis and Sam Mitchell have already confirmed they will retire at the end of the season, while Drew Petrie is set to join them.
The futures of Mark LeCras, Josh Hill, Sharrod Wellingham, and Eric Mackenzie remain up in the air.
