Indian athlete Manju Bala's Asian Games women's hammer throw bronze, which she won Sep 28, was Friday upgraded to silver after China's Zhang Wenxiu, who won the gold, was stripped of the medal following a failed dope test.
A sample taken from Zhang Sep 26 was found to contain the banned substances Zeranol and its metabolite. Zeranol is approved for use as a growth promoter in livestock, reports Xinhua.
"The competitor has been disqualified from the competition as well as these Games and as such her accreditation cancelled, and gold medal was withdrawn," said an Olympic Council of Asia (OCA) statement.
The disqualification means the gold will now go to Zhang's compatriot Wang Zheng, the silver to Manju and the bronze to Japan's Aya Masumi.
