Jockey Jordan Williams has been banned for six months after testing positive for cocaine.
Williams, 25, faced an independent disciplinary panel on Thursday following a breach of the British Horseracing Authority’s (BHA) Rules of Racing.
The rules state a jockey must ensure that no banned substances are present in their body.
Williams was selected for a random drugs test at Kempton on 7 February.
The jockey provided a hair sample that showed cocaine had been ingested between December and February.
Williams admitted the breach and the independent panel issued a six-month ban, the BHA said.
His period of ineligibility was backdated to start on 11 March 2024, when his interim suspension began following the positive test result.
