Fremantle announces the delisting of Dillon O'Reilly and Isaiah Butters despite four rounds to go in the 2020 season.

"Given that the players will not be required in the Cairns High Performance Centre, Dillon and Isaiah have both been released from Fremantle's football program training requirements for the remainder of the 2020 season," Dockers general manager of football Peter Bell said.

"Both players have been committed and dedicated to our cause in 2020, but as they would not be offered contract extensions for next season, it was decided it was in the best interest for all parties to avoid unnecessary travel to the hub, living under AFL protocols and undergoing a mandatory 14-day quarantine upon their return to Western Australia."
