Champion jockey Silvestre de Sousa will likely be on the sidelines.
De Sousa was injured in a fall at Chelmsford on August 23 and at one stage it seemed he could be back in time for the next week’s St Leger meeting at Doncaster.
However, the Brazilian is targeting Champions Day in Ascot as a likely comeback.
“There has been a little bit of confusion regarding the extent of my trauma and once I will return riding, so I’d like to clear some of that up,” he wrote in his website for Star Sports.
“I can confirm there was a small fracture to my collar bone as well as a very small chip to one of these bones in my lower neck.
“All of that, along with lots of bruising (my lower back is still sore), signifies there isn’t any chance of me returning to ride at next week’s St Leger assembly.
“My aim remains to be riding in that very first week of October ahead of Champions Day.
“I’ve already started the rehabilitation process and have been at Peter O’Sullevan House here in Newmarket three times already this week.
“It’s about rebuilding the tissue and building up my strength along with the hydro pool is excellent for that.
“I shall continue to go there every day now and expect to attempt to get back to a horse in a couple of weeks or so.
“In my head, I’d love to attempt to be work at least three weeks from now – that is the hope anyway.”
