Doping in Tennis: British Player Tara Moore Banned for Four Years

British tennis player Tara Moore has been handed a four-year ban for committing an anti-doping rule violation under provisions of the Tennis Anti-Doping Program (TADP). The sanction follows the Court of Arbitration for Sport (CAS) decision on July 15, 2025, which set aside a previous no-fault ruling issued by an Independent Tribunal in December 2023.

Moore was initially charged by the International Tennis Integrity Agency (ITIA) after her sample, collected during the Copa Colsanitas tournament in Bogotá, Colombia, in April 2022, tested positive for the anabolic steroids boldenone and nandrolone. She attributed the presence of said prohibited substances to the consumption of beef and/or pork while in Colombia.

After the Independent Tribunal concluded that she bore no fault or negligence, the ITIA appealed the decision before CAS. Upon review, the CAS Panel held that Moore failed to prove that the concentration of nandrolone found in her sample was consistent with the ingestion of contaminated meat and that she had not established that the violation was unintentional.

CAS upheld the ITIA’s appeal, set aside the Independent Tribunal’s decision, and imposed a four-year period of ineligibility. Moore’s cross-appeal was declared inadmissible.

The period of ineligibility began on July 15, 2025, the date of the arbitral award, with credit for the time she served under provisional suspension.
