Mystery surrounds an expletive-laden social media rant, aimed at Fremantle and attributed to their former player Shane Yarran.
Five days after the troubled Docker announced his AFL retirement, two posts appeared on a Facebook page that was said to belong to Yarran.

The posts took aim at the club culture at the Dockers, coach Ross Lyon and Brownlow Medallist Nat Fyfe.
Fremantle have issued a statement, saying they have been unable to make contact with Yarran.

But they added he contacted a club official in a text message to say he did not have a Facebook account.
"Despite numerous attempts, the club has not been able to talk directly to Shane Yarran regarding posts made from a social media account in his name," a club spokesman said.
"However, last night, Shane advised a club official via SMS that he did not have a Facebook account."
The account from which the posts were made has now been deactivated."
The least abusive of the accusations read: "Fremantle Dockers are the worst club in AFL history.
"It took me to be drafted by them to see with my own eyes."
A second post read (verbatim): "Fremantle Dockers is the fakiest AFL club in the combition ... promise you they will never win a premaship. OK, Ross Lyon, f---ing give it up."
Yarran is believed to be on holiday in the Kimberley.
He is facing assault-related charges over two separate incidents.
Fremantle boss Steve Rosich had said on Monday the club would continue to support Yarran in his retirement.
