The Court of Arbitration for Sport has imposed a four-year suspension on British doubles specialist Tara Moore after upholding an appeal by the International Tennis Integrity Agency. The panel ruled that Moore failed to prove that the anabolic steroid nandrolone entered her system through contaminated meat, overturning a December 2023 independent-tribunal finding that had cleared her of fault. Moore, 32, originally tested positive for nandrolone and boldenone at the Copa Colsanitas tournament in Bogotá in April 2022 and was provisionally suspended the following month. The new sanction starts 15 July 2025 but will be reduced by the 19 months she has already served, leaving her ineligible to compete until the start of the 2028 season. CAS dismissed a counter-appeal from the player, and its decision is final except for limited procedural avenues in Swiss courts.
