Dettori suffered injuries to his head and wrist when unseated from Wainwright in the Rose of Lancaster Stakes at Haydock a week last Saturday. Wainwright shattered a foreleg and had to be destroyed.
The jockey had originally hoped to ride in Sunday's Prix Jacques le Marois at Deauville but then delayed his return until the Ebor meeting at York, where he was originally booked to ride Needle Gun in today's International Stakes.
However, John Gosden, who retains Dettori, said yesterday: "He won't ride Tuesday, he won't ride Wednesday, but he will probably ride on Thursday.
"As he wasn't coming back tomorrow, he thought he would give Wednesday a miss as well - an extra 24 hours can make quite a difference. He'll have a couple of rides on Thursday but nothing too dramatic. He wants to get back in the swing of things by the end of the week.
"He rode out this morning and was still a bit stiff, and there is a big difference between riding out and riding in a race, which perhaps people don't appreciate."
Among Dettori's mounts on Thursday is So Factual in the day's highlight, the pounds 100,000 Nunthorpe Stakes. The five-year-old, representing the Godolphin partnership, is bidding for his second pattern race of the season after his narrow win in the Cork And Orrery Stakes at Royal Ascot in June.Reuse content
