Fremantle tagger Ryan Crowley has been de-listed by the Dockers.

Crowley was an integral part of Fremantle’s success of the past few seasons, before the 31-year-old was suspended for 12 months by the AFL Anit-Doping Tribunal after testing positive to a banned substance in July 2014.

He became available for selection for this year’s preliminary final, however, was not selected in the side.

Veteran Paul Duffield has retired, while Max Duffy, Josh Deluca, Jacob Ballard and Craig Moller have also been de-listed.

However, the club has committed to re-drafting Josh Deluca in the AFL Rookie Draft.
