The World Anti-Doping Agency has appealed against the decision to clear world number Jannik Sinner of blame after he twice tested positive for a banned substance.
Wada said the International Tennis Integrity Agency’s (ITIA) decision to exonerate the Italian in August was “not correct under the applicable rules”.
It has appealed to the Court of Arbitration for Sport (Cas) and says Sinner should be banned for “between one and two years”.
Sinner, 23, is currently playing Russian Roman Safiullin in the last 16 of the China Open in Beijing.
He was cleared of any wrongdoing after twice testing positive for low levels of a metabolite of clostebol – a steroid that can be used to build muscle mass – during the Indian Wells tournament in March.
He was provisionally suspended but Sinner challenged the decision and was able to continue playing.
The ITIA said in August that Sinner was inadvertently contaminated with the substance by his physiotherapist, Giacomo Naldi.
