The British Horseracing Authority has announced that it will visit the yard of Irish trainer Philip Fenton ahead of this year's Cheltenham Festival.
The BHA say they intend to interview the trainer and test the horses that he has entered for next month's Festival.
Fenton is preparing for a court case after being charged with possession of banned substances, including anabolic steroids.
Fenton says that the British Horseracing Authority are "more than welcome" to carry out tests at his yard.
The Fenton-trained Last Instalment is one of the favourites for this year's Cheltenham Gold Cup.
