Sara Moreira, Lim Hee-nam suspended

MONACO -- A Portuguese steeplechaser and South Korean sprinter were suspended after failing doping tests at the world championships in South Korea.

Sara Moreira and Lim Hee-nam tested positive for the banned stimulant methylhexaneamine in urine controls during the Aug. 27-Sept. 4 worlds in Daegu, the International Association of Athletics Federations said Friday.

Moreira finished 12th in the women's 3,000-meter steeplechase, while Lim ran on the 4x100 relay team that finished fifth in its heat.

The IAAF said the positive findings were confirmed in testing of the backup "B" samples. Both athletes have been "provisionally suspended" pending disciplinary hearings.

They were the only two positive cases reported from testing of 468 urine samples.

In addition, the IAAF collected a total of 1,849 blood samples, used mainly for monitoring an athlete's blood profile as part of the "biological passport" program.

The blood samples were first screened in Daegu and have been sent to the World Anti-Doping Agency lab in Lausanne, Switzerland, for more analysis, including for EPO and growth hormone.

IAAF president Lamine Diack said "the testing program in Daegu was an unprecedented success in terms of the number of samples collected."
