Serena Williams describes ‘grueling’ anti-doping rules in tennis ahead of Wimbledon comeback

Serena Williams, returning to Wimbledon for her first singles match in nearly four years, described tennis anti-doping rules as 'grueling' at her pre-tournament press conference on Sunday, expressing confusion about the protocols around missed tests. Under WADA rules, players must submit to testing when required by a doping control officer, even outside their designated availability window. Her comments came shortly after 2023 Wimbledon champion Markéta Vondroušová received a four-year ban for refusing a test conducted outside her specified one-hour availability window.
