Marketa Vondrousova, the former Wimbledon champion, insists she has “never doped” after the International Tennis Integrity Agency (ITIA) bans her from tennis for four years. Multiple outlets report that the ban is imposed by the ITIA following an anti-doping process in which Vondrousova is accused of failing to provide access to an anti-doping officer. One report specifies that the incident occurred in December 2025, when the ITIA says she did not open the door to the officer. The other accounts focus on her response, quoting or paraphrasing her assertion that she has never doped, in response to the sanction. The reported coverage does not include details of any alleged substance use; instead, it centers on the access-related allegation referenced by the ITIA. The dispute therefore centers on whether Vondrousova complied with the requirements of the anti-doping investigation, and her continued denial of doping.
