Iranian judo champion Saeid Mollaei is now in hiding after receiving a threat in his life.
Since leaving the Iranian judo team last month it has not been showing yet.
The Iranian government has ordered him not to take part in the world championship competition.
This is to prevent the risk of being confronted by Israel's stoning.
Mollaei is a defending world champion whose biggest rival is Israel's Sagi Muki.
As such, the Iranian judo team has yet to determine if it will ever participate in the Olympics.
