Aidan O'Brien has warned that a Qipco 1000 Guineas tilt for Found could be in doubt if fast conditions prevail at Newmarket.
The daughter of Galileo tops ante-post lists for both the Guineas and the Oaks after a brilliant display in Longchamp's Prix Marcel Boussac.
However, in a stable tour on the At The Races website, her trainer said: "She had a bit of a temperature a few weeks ago, so we eased off her a little bit. She's in good form now and will go to the Curragh for a little canter on Sunday."
O'Brien continued: " She's in all the Classics and I think she'll be quick enough for a mile, though Joseph (O'Brien) and Ryan (Moore) both think she'll get a mile and a half.
"The one thing is that she's a big filly and while I don't think she wants soft ground, she does have a round enough action and you wouldn't necessarily want to belt her off really fast ground at Newmarket this early in the season as she's a filly you'd look forward to through the whole year."
Qualify is another potential Guineas challenger and was last seen finishing a luckless eighth in the Breeders' Cup Juvenile Fillies Turf.
"She's a nice filly and we just weren't riding her right until we dropped her in behind in the Weld Park Stakes," said O'Brien.
"She loves fast ground and you'd imagine she'd get a mile and could even get a mile and a half in time.
"She's a big strong galloping filly and those Fastnet Rocks get better with age. We always thought she could be a Group One filly and hopefully she'll get there.
"She'll go to the Curragh on Sunday for a spin and we'll look at possibly starting her off in a Guineas trial with a view to running in the Newmarket 1000 Guineas."
One of the yard's more interesting older horses is Tapestry, who beat the top-class filly Taghrooda in last year's Yorkshire Oaks.
O'Brien said: "She's in good form and could possibly start back in something like the Tattersalls Gold Cup or the Coronation Cup. A mile and a half is probably her trip, but she could well get away with a mile and a quarter.
"I think she's done well from three to four, she's put on plenty of weight and looks stronger and bigger."
