SYDNEY has pre-listed Robbie Fox and Sam Gray as Category A rookies for the 2021 season.

Under new AFL rules, clubs are able to transfer two players from the primary to the rookie list, without having to go through the drafting process.

The rule change was introduced last week, just after the players were delisted by the club.
