A Belarusian weightlifter who was mysteriously withdrawn from the Rio de Janeiro Olympics has been suspended for alleged "urine substitution" in a doping sample.
The International Weightlifting Federation says Stanislav Chadovich is provisionally suspended awaiting a ruling on allegations of using substitute urine to fool a drug test.
At the Olympics, Chadovich was to compete in the men's 62kg category and was considered a potential medal winner.
However, he was removed from the Belarus team at short notice and with no explanation.
The IWF did not say whether the alleged offence occurred in Rio.
