"The AIU confirms (a) provisional suspension against... Bahraini long-distance runner Eunice Jepkirui Kirwa... for a violation of the IAAF's (International Association of Athletics Federations') Anti-Doping Rules," AIU said in a statement.
Kirwa becomes the second women's marathon podium finisher at Rio to test positive for the same substance after Kenyan gold medallist Jemima Sumgong, who was suspended for four years by her country's anti-doping agency (ADAK) in 2017.
Sumgong's ban was doubled to eight years by the AIU after the IAAF found her guilty of providing false information while defending herself against the initial sanction but was allowed to keep her gold medal as she tested positive in April 2017.
