Sydney delists Jackson Thurlow, Robbie Fox, Zac Foot and Sam Gray.
"Robbie, Zac and Jackson have all been outstanding people to have around the club and have made a contribution both on and off the field, so these were tough calls to make," Sydney football manager Charlie Gardiner said.
"The uncertainty surrounding the make-up of lists has made this period particularly challenging and all three have handled the situation with great character and maturity."
