TOKYO (AP) -- Japanese men's freestyle wrestler Takahiro Shimonaka has been suspended two years for a doping violation.
The Japan Anti-Doping Agency says traces of Tamoxifen were detected in Shimonaka. Athletes commonly use the drug to counter the side effects of steroids.
Kyodo news agency reported that Shimonaka told JADA he mistakenly took Tamoxifen, which belonged to a woman he lives with.
Shimonaka tested positive after Japan's national championships in December, when he won the silver medal in the men's 211-pound division.
