The local media have reported next season S-league will remain as 13-teams so FAS are not admitting any new members.
This is despite interest from National Football League (NFL) Division Two club Admiralty FC.
The club, who have secured promotion to the NFL Division One next season after a dominant season, had expressed interest in joining the S-League.
It is understood that Admiralty's team manager R Vengadasalam had been in discussions with S-League CEO Lim Chin on the
matter, since March but the chances they will be admitted look low.
