Charlie Appleby hopes William Buick will be back in the saddle next week after undergoing a series of hospital tests.
After riding the Appleby-trained Expressionist to victory at Ascot on Saturday, the Derby-winning jockey missed his intended mounts in France on Sunday after reportedly feeling unwell.
The 30-year-old, who is retained by Sheikh Mohammed’s Godolphin operation, elected to sit out this week, meaning he misses high-profile rides at York, including Line Of Duty in Thursday’s Al Basti Equiworld Dante Stakes and Ispolini in the Matchbook Yorkshire Cup on Friday.
Appleby said: “William is back out of hospital now and he is just having an easy week. He is just waiting for the test results.
“He came down with whatever it was at the weekend and it just knocked the wind out of his sails. Hopefully he will be back next week, then we can regroup.”
