English jockey Steve Drowne is to have further X-rays to gauge when he might be able to fly home from Hong Kong after being injured in a fall at Sha Tin.
Drowne punctured a lung a broke a collarbone when his mount Jwala suffered a fatal fall in Sunday's International Sprint.
The Robert Cowell-trained Nunthorpe winner appeared to be squeezed between horses and crashed to the ground.
Drowne was conscious before being taken to hospital where he remains.
Fellow jockey Rab Havlin said he spoke to Drowne on Monday.
"We knew he had a punctured lung and a broken collarbone and he's also got whiplash so he's got a collar on," Havlin said.
"I think they are going to X-ray him tomorrow and have a look at his lung and see when he can fly.
"In the best-case scenario he'll be able to fly back on Wednesday or Thursday, but if not he'll have to wait.
"He's sick about what happened to the filly and he just doesn't know when he's going home."
