Australian jockey Brett Prebble will miss an indefinite period after breaking his collarbone in a nasty fall at Sha Tin on Saturday.
Prebble fell from Telecom Top Star in the Tulip Handicap (1800m) when Howard Cheng allowed his mount Rocket And Gold to shift into Telecom Top Star's path at the top of the straight.
Stewards charged Cheng with careless riding and subsequently suspended him for seven meeting, which equates to nearly a month on the sidelines.
Meanwhile, another star Australian rider, Darren Beadman, captured the Group III Centenary Vase aboard the John Moore-trained Packing Ok.
Packing Ok had the perfect run before proving too strong for the Irish-bred Pure Champion. Beadman said Packing Ok's win justified the gelding's previous trainer John Hawkes's opinion of him when the trainer prepared him in Melbourne.
Packing Ok had two starts for Hawkes Racing in Victoria for a second and a comfortable maiden win under the name Packing Commander.
"When John Hawkes trained him in Australia he felt Packing Ok would make into a Group horse, so his judgement has been spot on," Beadman told the South China Morning Post.
"He showed that early potential and was able to win 1400 metres first-up here like a decent horse, but I do think he is still improving.
"I think he's going to be one of those very solid horses that just gets better with age. He took everything in his stride and got into a rhythm, nice and relaxed."
