The 26-year-old, who was champion jockey in 2019 and 2020 and who is on track to be crowned it a third time this year, apologized to fans on Twitter saying that he took “full responsibility” after taking the test at Newmarket Racecourse, England.
“I’m sorry to all the people I’ve let down today. I take full responsibility. I will be riding tomorrow.”
The alcohol limit for jockeys is 17 micrograms per 100ml of breath, whereas the UK driving limit is 35 micrograms per 100ml.
The latest incident has now been referred to the British Horseracing Authority (BHA).
“Murphy, the Equine Welfare Integrity/Collection Officer, and Raceday Assistant were interviewed.
“Having heard their evidence, the matter was referred to the Head Office of the British Horseracing Authority for further consideration and Murphy was stood down for the remainder of the day.”
