Odds-on favourite Hay List is under an injury cloud ahead of the group one William Reid Stakes at Moonee Valley.
Trainer John McNair advised stewards yesterday that the last-start Newmarket Handicap winner had been treated for a bruised near-fore heel.
Hay List eased marginally from $1.35 favouritism to $1.40 for tomorrow night's William Reid (1200m) after stewards scheduled a veterinary inspection of the gelding today.
Buffering, who was beaten in a photo-finish by Hay List in the Newmarket at Flemington on March 10, firmed from $10 to $9.
Lone Rock who is one of the outsiders at $31 with TAB Sportsbet has drawn barrier five alongside Hay List in four in the eight-horse field.
