Jannik Sinner faces potential Wimbledon ban after WADA appeal but can play Australian Open

Jannik Sinner may face a ban from Wimbledon after the World Anti-Doping Agency (WADA) appealed a decision that cleared him of doping charges. He tested positive for a banned steroid in March but explained it was due to a massage. The appeal could lead to a suspension of up to two years, but Sinner is still allowed to compete in the Australian Open in January. A hearing is expected before the French Open in June. WADA's director general noted that improved testing methods may explain the rise in doping cases, suggesting that many findings involve very small amounts of substances.
