Oisín Murphy says his planned return to action at Lingfield on Friday following a three-month suspension has been delayed due to an administrative error.
The champion jockey was banned after a drugs test at Chantilly in July showed metabolites of cocaine. He strenuously denied taking the drug and requested a B sample.
The Kerry native was due to take up three rides on Friday and a further five at Chelmsford on Saturday but posted on Twitter: "At 18.50 yesterday I was personally informed by the BHA due to an administrative error I will not be able to partner my rides at Lingfield today and Chelmsford on Saturday.

"I'm currently looking into this situation with the BHA and I plan to be back on the racetrack as soon as I possibly can. I apologise profusely to all the owners, trainers and supporters who I'm having to let down at such late notice. It's 128 days since my last ride in the UK."
