Serena Williams called it “unprofessional” - Anti-doping body pushes back
Tennis’ anti-doping body responded after Serena Williams called the system “unprofessional,” clarifying how the rules actually work.
Serena Williams’ return to Wimbledon has everybody talking, but not just for what she might do on the court. Ahead of her first singles appearance at the tournament since 2022, Williams sparked a fresh debate by calling tennis’ anti-doping system “unprofessional” and “unreasonable”.
The comments quickly made waves, especially given her status as one of the sport’s most respected voices. But it didn’t take long for tennis officials to respond.
What Serena Williams said
Speaking before the tournament, Williams described the testing process as “grueling”, pointing in particular to how missed tests are handled. She suggested that even being unavailable outside a designated testing window could count against a player, adding that the system makes it difficult to manage a busy life off the court.
“I’m like, I guess I can’t go pick up my kids,” Williams said, explaining her frustration with the rules.

While she acknowledged that anti-doping measures are necessary, she questioned whether the current system goes too far.
Why the ITIA pushed back
The International Tennis Integrity Agency (ITIA), which oversees anti-doping in tennis, quickly clarified that Williams’ understanding of one key rule was not accurate. According to the ITIA, a missed test only counts as a violation if a player is unavailable during their designated one-hour window. If a tester cannot reach a player outside of that window, it does not count as a strike.
So the scenario Williams described, being penalized for missing a test outside her scheduled time, is not how the system is supposed to work. The organization also emphasized that the rules have not changed in recent years, directly addressing Williams’ suggestion that new guidelines may have been introduced.
Why this system exists
Like many global sports, tennis uses a “whereabouts” system that requires players to provide a daily one-hour window for potential testing. The goal is to allow for no-notice testing while still giving athletes a defined period when they must be available. Missing three tests within a 12-month period can lead to disciplinary action.
The ITIA defended the system as a necessary safeguard, stating that it is designed to protect clean competition rather than create unnecessary penalties.
Anti-doping procedures have long been a point of tension across sports, especially when it comes to balancing enforcement with athletes’ personal lives. Williams is not alone in her frustration with the system either, particularly sharing with those juggling travel, family responsibilities, and business ventures alongside their careers. At the same time, governing bodies continue to stress that unpredictability is essential for effective testing.
