Peter Robl is expected to be discharged from Westmead Hospital on Friday but will be sidelined for at least six weeks after scans revealed he suffered a fractured vertebra in his neck in a three-horse fall at Rosehill on Wednesday.

Robl, Melbourne Cup-winning jockey Blake Shinn and Jeff Lloyd were all injured in the pile-up near the 350 metres of the Dalkia Handicap.

Shinn is expected to return to action at Friday's Randwick twilight meeting while Lloyd is likely to return on Villiers Stakes day on December 20.

Amazingly, the fall occurred just one race after Shinn's girlfriend Kathy O'Hara fell from Hit The Post near the same spot in the Computer Air Handicap.

O'Hara is suffering from bruising but is also expected to ride at Randwick on Friday.

Lloyd stayed in hospital Wednesday night but was discharged Thursday after being heavily concussed in the incident and his manager Bryan Haskins said his client would most likely take a one-week overseas holiday.

"He was booked to go to Fiji with his family this week anyway, so I think he'll be going over there and taking it easy for the week but he'll be back for the Villiers the weekend after," Haskins said.

Shinn's manager Reece Murphy said the hoop had a sore left wrist and forearm but was in good spirits.

"He's doing well, he had scans last night and that showed no breaks and he's getting a little bit more work with a sports doctor but should be right for the twilight meeting," Murphy said.

"Blake said Kathy is going well too and she'll be right to ride at Randwick."

Robl's wife Elaine said the feeling in her husband's right side had come back.

"He had some numbness last night but everything's fine on that front but he will be out for at least six weeks and possibly eight," she said.

"It's such a huge relief that he's okay, it was a shocking fall and it's good to hear everybody else is on the mend as well."

Robl had an MRI scan on his spine late Thursday.

"They want to give him a final check and make sure there are no other problems," Elaine Robl said.

Stewards opened an inquiry into the three-horse fall but the matter was adjourned to allow the injured riders to be present at the hearing.

Meanwhile, Tommy Berry has appealed his charge of careless riding for contributing to O'Hara's fall.

Berry was ruled by stewards on Wednesday to have contributed 60 per cent to the fall after shifting out on his mount Royal Stash and was hit with a nine-meeting suspension which begins Monday.

Nash Rawiller, who pleaded not guilty to careless riding and contributing 40 per cent to the fall, did not lodge an appeal with Racing NSW.

Rawiller was given eight meetings, commencing on Sunday and ending on January 1.

Stewards said Rawiller permitted his mount, race winner Tullamarine, to shift in contributing to O'Hara'a mount Hit The Post being crowded for room.

Hit The Post had to be put down after falling heavily.
