Singapore Athletic Association (SAA) general manager Ong Yeok Phee is set to leave the organisation a second time after tendering his resignation last month.
The former national sprinter, 59, had been in the post since Oct 2010.
Ong (above) is understood to be overseas and could not be reached for comment, but SSA president Tang Weng Fei confirmed the news.
"He tendered his resignation before our AGM (Annual General Meeting) on Thursday," said Tang, who is currently in Hong Kong.
"But I haven't spoken to him or my exco about it, so I'll have to do that first when I come back to Singapore."
Tang, who will return this Thursday, only said that he believed Ong's intention to leave was because of "personal reasons".
The 58-year-old oil trader added that there are still several procedures the SAA have to undergo before resolving the issue of Ong's resignation.
Ong - who was part of the 4x400m relay team that took the 1974 Asian Games bronze in Teheran - was the Singapore Amateur Athletic Association's honorary secretary from 1988 to 1994, and then its general manager until 1997.
He left the association to become the general manager of S-League side Geylang United and returned to the SSA in Oct 2010.
