MONACO (AP) Croatian-American marathon runner Lisa Nemec and Belarusian race walker Hanna Drabenia, who both competed at the 2012 Olympics, have been banned for doping, the IAAF said Thursday.
Nemec, formerly known as Lisa Stublic, grew up in Connecticut and raced for Columbia University but competes for Croatia, where she has set numerous national records. She finished 52nd in the marathon at the 2012 Olympics.
The IAAF said Nemec has been banned for four years following an out-of-competition doping test taken in October.
Drabenia picked up a two-year ban following a failed test at a competition last year in Belarus. She has raced at various major international competitions and was 24th in the women's 20-kilometer walk at the 2012 London Olympics and 16th at the world championships a year later.
The IAAF also ruled that Cuban-born hurdler Orlando Ortega will not be able to compete at the Olympics in August after he defected and switched allegiance to Spain.
The IAAF said Ortega, who won bronze for Cuba in the 110-meter hurdles at the 2011 Pan-American Games, will only be able to represent Spain officially from November, ruling him out of the Olympics in Rio de Janeiro.
