MOSCOW (AP) -- Three Russian athletes have been disqualified from the 2012 Olympics after failing doping retests, the country's track federation said.
Hammer throwers Maria Bespalova and Gulfiya Khanafeeva, and triple jumper Viktoria Valyukevich were all disqualified. None of them were medalists.
The disqualifications of Bespalova and Khanafeeva mean all three Russian women who competed in the hammer throw in 2012 have tested positive for doping. Tatyana Lysenko was the original winner, but was stripped of her gold medal in October.
Valyukevich, a former European indoor champion, was eighth in the triple jump at the 2012 Olympics and finished two places ahead of Russian teammate Tatyana Lebedeva, who has been stripped of two medals from the 2008 Beijing Games for doping.
