Blight has been delisted.
I don't think Hall was delisted. The Swans just made it public that he would be traded at season's end.
I'm certain that if a player is delisted, then that's it. They're off that clubs list and can't be used in a trade.
Hall officially retired but remained on the list just and could have potentially stayed there until the cutoff date after trade week but before the draft
I dare say Blight has simply been told he'd be delisted at this stage pending trade week outcomes.
