World number one Jannik Sinner is facing the renewed threat of a ban after the World Anti-Doping Agency launched an appeal against a ruling of “no fault or negligence” for two positive tests he returned in March.

Sinner, who won the US Open earlier this month, twice tested positive for an anabolic steroid in March but on August 20 the International Tennis Integrity Agency determined he was not to blame and imposed no punishment.
