Nine Sydney jockeys have been prevented from riding at Tuesday's Gosford meeting after a well-known Sydney hoop who competed at Rosehill on Saturday began to show flu-like symptoms.

While the prominent rider is awaiting test results for COVID-19, Racing NSW stewards announced Andrew Adkins, Brenton Avdulla, Tim Clark, Sam Clipperton, Jason Collett, Robbie Dolan, Adam Hyeronimus, James Innes Jr and Rachel King were not permitted to ride at Gosford.

All of the jockeys were involved in Saturday's meeting at Rosehill.

“A jockey who rode at Rosehill on Saturday is now showing flu-like symptoms and as a matter of caution we've asked all jockeys who rode at Rosehill on Saturday not to ride at Gosford today until the results of that jockey's tests are known,” Racing NSW chief steward Marc Van Gestel said.

“Once we get those results we'll be able to release a detailed plan as to how we go forward depending on the results.”

Van Gestel said they were hopeful of getting the result of the jockey's COVID-19 test back by Tuesday afternoon.
