Outsider Diore Lia has been declared for the Investec Derby at Epsom on Saturday, despite originally being pulled out of the race.
Original jockey Gina Mangan was prohibited from riding in the race on Wednesday by the British Horseracing Authority.
Mangan has yet to win a race in the UK and she has no experience of riding at Epsom and the BHA claimed her ban protected “the best interests of the sport“.
However, apprentice jockey Paddy Pilley will now get the ride with Diore Lia priced at 1000/1 with most bookmakers.
The maiden filly is owned by Mary Todd and her brother Richard Aylward is keen to run the three-year-old in order to generate publicity for Great Ormond Street Children’s Hospital.
He told Press Association Sport: “She’s definitely running and Paddy will be riding her.
“Our filly is the people’s champion now and I hope everyone gets behind her.”
