Georgian shot putter Benik Abramyan has been provisionally suspended and will miss today's competition at the Tokyo Olympics after failing a doping test for steroids, the International Testing Agency (ITA) said.
The 36-year-old, who also competed at the Rio de Janeiro 2016 Olympics, tested positive during an out-of-competition test conducted on 31 July in Tokyo.
He can now demand his 'B' sample be tested, the ITA said.
"The athlete ... has been informed of the case and has been provisionally suspended until the resolution of the matter," it said in a statement.
The ITA is in charge of testing for banned substances at the games.
This is the second anti-doping rule violation at these games.
Nigerian sprinter and 2008 Olympics long jump silver medallist Blessing Okagbare was also provisionally suspended after a positive test for human growth hormone three days ago.
