Serena Williams has quietly re-entered the International Tennis Integrity Agency’s (ITIA) registered testing pool for the first time since 2022, a procedural move required of any player contemplating a competitive comeback. The 23-time grand slam singles champion, 44, has not played an official match since her third-round exit at the US Open more than three years ago.
Williams filed paperwork with the ITIA in September 2022 that exempted her from the sport’s stringent whereabouts requirements, describing her departure as 'evolving away' from tennis rather than a hard retirement. To return to competition, players must make themselves available for out-of-competition testing for six months before entering an event.
Her name appeared on the ITIA’s updated testing-pool list dated 6 October. An ITIA spokesperson confirmed to the Guardian that Williams had requested reinstatement, but emphasised that a place on the list was not itself evidence of a comeback. 'Serena Williams is back on the Registered Testing Pool list,' the spokesperson said, noting that athletes returning from retirement must be available for testing for six months under World Anti-Doping Agency rules.
Later on Tuesday, Williams disputed that her inclusion signalled any plans to return, writing on X: 'Omg yall I’m NOT coming back. This wildfire is crazy.' A representative for Williams did not respond to questions about her intentions.
People familiar with the process told the Guardian that Williams explored a return earlier this autumn, with an attempt to rejoin the testing pool in August, likely to play doubles with her sister Venus. Those plans dissipated when it became clear the six-month testing window could not be waived, a restriction that blocked Andy Roddick from a similar cameo in 2014. Venus Williams, 45, never formally retired and returned this summer after a 16-month break.
Williams’s reappearance on the ITIA list restores her eligibility timeline. If she remains in the pool without interruption, she could enter tournaments as early as mid-2026. Whether she intends to contest singles, reunite with Venus in doubles, or simply preserve the option remains uncertain.
