Fremantle has informed defender Ryan Nyhuis and ruckman Scott Jones their contracts have not been renewed for the 2020 season.
Nyhuis played 17 games for the Dockers over his four seasons with the club, while Jones featured just six times.
“We thank both Ryan and Scott for their efforts at Fremantle,” Dockers general manager of football operations Peter Bell told the club's website.
“Both were held in high regard at Fremantle and displayed excellent professionalism and commitment in their time as Fremantle Dockers.”
The pair join Shane Kersten and Harley Bennell on the outgoing list, after the pair were delisted during the season.
