Fremantle could potentially lose both Brad and Stephen Hill during the upcoming off-season, with the pair linked to moves away from Perth.

Brad Hill, who won three premierships with the Hawks before moving to Fremantle at the end of the 2016 season is reportedly once again set to seek a trade back to Hawthorn, as he did last season.

According to Fox Sports, Hill is set to ask for the trade once again, and hope for a different outcome than last season, when the Dockers denied his request and forced him to remain at the club.

Hill is still contracted until the end of the 2021 season, so the Dockers still have the upper hand when it comes to his future.

In regards to Hill's older brother Stephen, the 29-year-old is an unrestricted free agent at season's end, and is expected to be chased hard by the Suns, who are looking to add outside run to their side.

Hill has spent his entire 204-game career at the Dockers spanning back to the 2009 season, while younger brother Brad has played just 44 games for the club across his three seasons in Perth.

Fremantle take on Melbourne at the MCG on Saturday afternoon.
