Group One winner Fenway is under an injury cloud ahead of Saturday's $1 million ATC Australian Oaks.
The Lee and Shannon Hope-trained filly had a pulse in her near fore hoof on Wednesday.
The trainers reported to stewards that the filly was found to be lame in that hoof and missed a gallop.
The last-start Vinery Stud Stakes winner will be inspected by Racing NSW's senior vet Dr Craig Suann on Friday.
Fenway is on the second line of betting for the Oaks at $5.50 behind Winx at $4.60.
