Full Stop Australia chief executive Karen Bevan said the club had taken action on standards in August and the awards night was a chance to show those standards were still being upheld.
"In August the club took action on standards," Ms Bevan said. "[The awards] were a chance to show those standards are still being upheld."
Heeney and teammates Chad Warner, Nick Blakey and James Jordon all featured in the top 10 of polling for the medal, which the club earlier this week recast as an award for the Swans' "most valuable player".
The four players remain persons of interest in an unfolding investigation by Victoria Police into allegations of sexual assault made by three exotic dancers in a suite of the Pullman Hotel in the pre-dawn hours of August 17.
All of the men deny any wrongdoing and maintain their innocence. No charges have been laid, and the police investigation is ongoing.
The club has defended the players' eligibility, with the club boss saying they deserve the presumption of innocence, according to reporting from the awards night.
