Visiting English jockey Tom Marquand has been cleared of any injuries to his shoulder or neck after a fall at Randwick where he rode a Group Three double.
Marquand will, however, have to undergo a concussion test before he can ride again.
After riding two-year-olds Away Game and Prague to their respective wins in Saturday's Widden and Canonbury Stakes, Marquand came down when Ronstar suffered a fatal injury later in the day.
Both Away Game and Prague are trained by Ciaron Maher and David Eustace and are well in Golden Slipper markets headed by stablemate Cellsabeel who will take her place in the $2 million Inglis Millennium on Saturday.
Marquand is coming to the end of his stint in Sydney but said he would be happy to return for a ride in the Slipper on March 21 and Maher said he would be equally happy to pay his air fare.
The Gary Portelli-trained Ronstar was a stable favourite who won three of his 16 starts and more than $250,000 prize money.
"RIP Ronstar. Swayback jack as he was affectionately known in our stable, gave us and his owners so much enjoyment. An absolute gentleman of a horse and he will be sorely missed" Portelli tweeted.
