A Belarusian weightlifter who was mysteriously withdrawn from the Rio de Janeiro Olympics has been suspended for alleged "urine substitution" in a doping sample.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.
It comes as Belarus already faces a one-year ban from international weightlifting after several lifters failed retests of their doping samples from the 2008 and 2012 Olympics.
