The award ceremony was supposed to take place yesterday but has been postponed due to "an ongoing investigation", writes AP.

According to the Russian RBC, Valieva has tested positive for trimethazidine, a drug that can help increase endurance and increase blood flow efficiency.

The remedy is the same as the swimmer Sun Yang was suspended for when a test result was destroyed with a hammer and is on Wada's banned list and used for heart problems.

A couple of hours after the information began to circulate, Valieva, who became the first woman to do a quadruple in an Olympics, trained as usual and the Russian team was silent with comments.

- She is not suspended, says the Russian team's spokesperson.

A positive test could mean that the Russian team is washed and gets rid of the gold.

It would also mean that the big favorite Valieva, who won the European Championships in Tallinn a couple of weeks ago, is not allowed to start in the individual program that starts in a week.

The test must have been taken before the European Championships in Tallinn in mid-January.

"Do not want to participate in speculation"

- It would be inappropriate to comment on an ongoing process and I do not want to participate in the type of speculation that took place during the night, says IOC spokesman Mark Adams.

It is unclear if Valieva applied for an exemption to take the drug and if she has heart problems from having to use it.

The fact that she is also under 16 years of age means that she is extra protected as a minor according to the doping regulations and can receive a milder punishment if she is considered guilty.

It is unclear how the International Skating Federation, ISU, will act around the European Championship gold.

The Swiss-based testing company ITA, which is controlled by the IOC, does not want to comment on the case.

ISU can also go in and test active, which would have happened before January 27 when ITA took over the testing before the Olympics. 

Several legal teams are working on the case.

- For the sake of understanding, let us wait for some explanations either from our sports leaders or from the IOC, says Kremlin spokesman Dmitry Peskov.
