Doping ban for Croatian-American marathon runner Nemec

MOSCOW (AP) The IAAF says Croatian-American marathon runner Lisa Nemec and Belarusian race-walker Hanna Drebenia, who both raced at the 2012 Olympics, have been banned for doping.
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 says Nemec has been banned for four years following an out-of-competition drug test taken in October.
Drabenia picked up a two-year ban following a failed test at a competition in Belarus last year. 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.
