South Korean sprinter Lim Hee-nam and Portuguese steeplechaser Sara Moreira both received six-month bans after failing doping tests at last year’s world championships in South Korea.

Moreira and Lim tested positive for the banned stimulant methylhexaneamine in urine controls during the Aug. 27-Sept. 4 worlds in Daegu, and were already suspended by the International Association of Athletics Federations.

Moreira’s suspension runs until March 7, and Lim’s until April 10.

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.
