Gabriella Papadakis and Guillaume Cizeron will not defend their ice dance title at the world figure skating championships in March.
Olympic weightlifting champion Nijat Rahimov of Kazakhstan has been charged with swapping his urine samples, which could threaten his gold medal.
The ITA also charged Dumitru Captari of Romania -- who competed alongside Rahimov in the under-77 kg event in Rio de Janeiro - with offences that took place "over a period of time in 2016". Both athletes have been provisionally suspended but it is unclear if the allegations span the 2016 Rio Games where Rahimov claimed gold with a world record lift.
