Here's the regulation as written. I'd check with a warden to be certain on the issue of having to be naturally attached to the carcass and the definition of "accompany the animal".
RETENTION OF EVIDENCE TO IDENTIFY SEX, SPECIES AND HORN OR ANTLER DEVELOPMENT OF BIG GAME ANIMAL HARVESTED.* * Any person who takes any big game animal in a hunt area where the taking of either sex, species, or antler or horn development is controlled or prohibited by regulation shall comply with this section while said animal is in transportation from the site of the kill to the residence of the person taking the animal, or delivered to a processor for
processing.
(a) In hunt areas where the taking of any big game animal is restricted to antler point or horn
size by regulation, the antlers or horns shall accompany the animal as a whole, or edible portion thereof.
(b) In hunt areas where the taking of any big game animal is restricted to a specific sex of animal by regulation, either the visible external sex organs, head or antlers shall accompany the animal as a whole, or edible portion thereof.
(c) In hunt areas where the taking of a species of deer is controlled or prohibited by regulation, either the head or the tail of the deer shall accompany the animal, or edible portion thereof as evidence of the species taken.
