Treve scanned after defeat
Treve has been undergoing tests since her return to France following her shock defeat in the Prince of Wales's Stakes at Royal Ascot.
Last year's brilliant Prix de l'Arc de Triomphe winner could only finish third behind The Fugue on Wednesday, having lost her unbeaten record at the hands of Cirrus Des Aigles in the Prix Ganay on her seasonal debut.
Treve appeared not to move well to post in the hands of Frankie Dettori and looked ill at ease during the race, though she did stay on at the end of the mile-and-a-quarter Group One to take minor honours.
"She's been for a scan and we have to wait for the results now," said trainer Criquette Head-Maarek.
The four-year-old filly went back home to Head-Maarek's stables in Chantilly and has been treated by Duncan Moir, the vet for owners Al Shaqab Racing.
Al Shaqab's racing manager Harry Herbert speculated after the race that Treve might have pulled a muscle before taking to the famous Ascot turf.
Herbert is optimistic she will return in the autumn to defend her Arc crown.
He said: "She was a bit sore at the top of her back into her quarters, so probably when she did a couple of kicks in the pre-parade ring it might have just tweaked something there.
"It's nothing serious, but there's a need for recuperation and she'll be trained for the Vermeille at Longchamp and then the Arc, hopefully."
