Wong Sai Kong (born 19 September 1978) is a Malaysian footballer who plays for Sarawak FA in Malaysia Premier League. He is also a former member of Malaysia's national team.
Sai Kong previously played for Negeri Sembilan FA from 2000 until 2001. During the 2000 season, Sai Kong helped Negeri Sembilan FA into the Malaysia Cup final but they were beaten 2–0 by Perak FA in the final. He later moved to Sarawak and took the team to the 2004 Malaysia Super League after defeating Melaka Telekom in the Super League Playoffs.[1]
After spending three seasons with Sarawak FA, Sai Kong signed with Selangor Public Bank. With the club side, he failed to score any league goals although he managed to score two goals during the Malaysia FA Cup.
