Fremantle have confirmed a trio of train-on players will pursue a list spot at the Dockers after joining the club's pre-season program during the Supplemental Selection Period.

Former Essendon forward Patrick Voss, Woodville-West Torrens youn gun Max Beattie and local product Sam van Rooyen will also be in contention for a vacant position at Cockburn over the coming weeks.

The Dockers have already signed ex-Gold Coast youngster Jeremy Sharp to their list through the SSP, which opened on Monday and will run until mid-February across two signing windows.

Voss has made the move west after a strong season with Essendon's VFL program, claiming best and fairest honours in his second season at Tullamarine after booting 30 goals from 17 games at the state league level.

Standing at 194cm, the big-bodied forward could be the top contender to join Justin Longmuir's ranks, however will have some competition from fellow attackers Beattie and van Rooyen.

Beattie has linked up with Fremantle after a promising year with the Eagles in the SANFL, where the 20-year-old averaged 14.3 disposals, 3.7 marks, 3.3 tackles and over a goal per game in 2023.

A former Murray Bushrangers talent, Beattie made the move to South Australia after being overlooked for last year's AFL Draft.

The younger brother of Melbourne key forward Jacob van Rooyen, Sam was not selected at the National Draft earlier this month after a promising year for WAFL club Claremont.

Across 14 games for the Tigers' premiership-winning Colts side, van Rooyen kicked 22 goals and averaged 8.7 disposals playing alongside drafted teammates Dan Curtin, Joe Fonti and Zane Zakostelsky.

A chance on an AFL list remains up for grabs for the 193cm teenager, who could remain in WA if successful in his training stint with the Dockers.

Fremantle noted a need for further forward options ahead of the draft and went on to secure South Australian small forward Jack Delean at the National Draft before adding local tall Odin Jones last Wednesday to their rookie list.

The club opened up two further list spots by moving Josh Corbett (hip) and Sebit Kuek (knee and shoulder) to the inactive list as their pair continue to recover from separate ailments.
