However, Crowley will be free to play later this season, after he accepted a voluntary suspension in late September last year.
That means that Crowley’s ban will end on September 24, meaning that he is eligible to play in the Preliminary Final and Grand Final weekends.
He can resume training with the Dockers two months before his suspension ends.
Crowley failed a drugs test after the Dockers’ round 17 game in mid-July last year, after testing positive to a banned substance.
The substance was contained in a pain killer which was not prescribed by Fremantle.
Crowley admitted he had made a huge mistake and deeply regretted his actions.
“I am deeply remorseful and disappointed with the mistake that I made last year,” Crowley said in a statement.
“I genuinely never intentionally meant to do the wrong thing.
“In the 13 years I have been playing for Fremantle I have never wanted to jeopardise my career and position at the club, or let any of my team mates or fans down. And for that I hope you will accept my deepest and sincerest apology.”
“That being said, I respect the decision of the tribunal and I look forward, hopefully, to playing for the Fremantle Football Club once again.”
