Fremantle star Hayden Ballantyne is the latest Docker said to be exploring his trade options.
Fairfax reports that Ballantyne has told his closest connections that he could leave the club at season's end, despite being contracted until the end of 2017.
After a hugely disappointing season, several Dockers could be on the way out, with Chris Mayne and Zac Clarke linked with trades, while reports emerged yesterday that reigning Brownlow Medalist Nat Fyfe is also set to explore his free agency options.
Ballantyne is understood to even be willing to join Fremantle's fiercest rival, West Coast to end his career.
The 29-year-old has kicked 220 career goals in 138 games with the Dockers.
