British tennis player Tara Moore was handed a four-year anti-doping sanction by the Court of Arbitration for Sport (CAS) on Tuesday.

Moore tested positive for the anabolic steroids boldenone and nandrolone following a tournament in Colombia in April 2022. The 32-year-old was provisionally suspended at the time, but an independent tribunal ruled in December 2023 that Moore bore no fault or negligence.

However, the CAS confirmed on Tuesday that it has upheld the appeal made by the International Tennis Integrity Agency (ITIA). Moore had made a counter-appeal, arguing that the presence of the banned substances in her system were caused by food eaten while in Colombia.

Moore, the No. 1-ranked doubles player in Britain when she was provisionally banned, will be subject to the four-year ban minus 19 months already served. She will not be eligible to compete again until the start of the 2028 season.

'For the ITIA, every case is considered according to the individual facts and circumstances,' ITIA chief executive officer Karen Moorhouse said. 'Our bar for appealing a first instance decision is high, and the decision is not taken lightly.

'In this case, our independent scientific advice was that the player did not adequately explain the high level of nandrolone present in their sample. Today's ruling is consistent with this position. We understand that players and their support teams may have questions about this decision, and we will answer these fully once we have reviewed the details of the ruling.'

Moore's suspension follows on the heels of World No. 1 Jannik Sinner serving a three-month anti-doping ban earlier this year. Former women's world No. 1 Iga Swiatek served a one-month suspension after testing positive for the prohibited substance trimetazidine in August 2024.

Moore has competed primarily on the ITF World Tour since returning in April 2024.
