KUALA LUMPUR (AFP) - Tajikistan defender Khurshed Beknazarov was slapped with a two-year suspension for doping violations on Thursday, after he tested positive during the Asian Games.

The suspension was handed out by the Asian Football Confederation after the 20-year-old was kicked out of the Games in Incheon, South Korea for testing positive for methylhexaneamine in their 1-0 Group C win over Singapore on Sept 14.

The drug is widely found in dietary supplements and sporting authorities say it is increasingly common among professional athletes.

Beknazarov, who can appeal against his suspension, was one of six athletes to fail drug tests at the Asian Games in September and October.

While Singapore failed to advance to the knockout phase, Tajikistan lost 2-4 to Iraq in the last 16.
