Fremantle Signs Mason Cox on Two-Year SSP Deal

The 34-year-old premiership ruck joins as depth behind the DarcyJackson pairing.

Overview

  • Fremantle confirmed the pre-season supplementary signing a month after Collingwood delisted the 211cm American.
  • The move fills a ruck cover need created when back-up Liam Reidy left for Carlton during the trade period.
  • Cox is not expected to feature regularly at senior level unless injuries strike, with teenager Aiden Riddle also developing behind the established pair.
  • List boss David Walls highlighted Cox’s experience and mentoring value, while Cox said he was very excited to make the move west and reunite with coach Justin Longmuir.
  • The former Magpie has played 139 AFL games, was part of Collingwood’s 2023 premiership, and appeared 10 times in 2025 largely as a forward.
