As per established racing practice replacement jockeys took their respective places for Races 5, 7, and 8 (Dillon) and 10 (Domeyer).
Such occurrences and practices are commonplace in the racing world, with several jockey changes per race card not unusual.
In this instance, due to an administrative oversight, some of the changes were unfortunately not communicated to our racing partners. Following an internal inquiry the standard operating procedures for jockey changes have been revised to ensure that such an administrative and communication error will not recur.
Phumelela Group CEO, John Stuart said: “We would like to thank our partners, whose fees, commissions and royalty payments help fund the sport of Horseracing in South Africa, for their understanding and, in the interest of maintaining relationships that are based on mutual trust and commitment, wish to reassure all of our stakeholders that such an occurrence will not happen again.”
