Mike Moroney has confirmed that talented three year old Quarterbar will not run in the Group One Queensland Derby at Eagle Farm on Saturday.

Moroney said that Quarterbar had been taken out of the Derby because of a tendon injury.

The scratching comes as a bitter blow for Kiwi jockey Chad Ormsby. Quarterbar was his only ride for the day.

Quarterbar was the winner of a three year old handicap last start at Doomben and was rated a $21.00 chance in the Derby before being withdrawn.

While Moroney and Ormsby have been left without a runner in the Derby, the scratching of Quarterbar has opened the door for the John Thompson trained From London to gain a start.

From London finished dead last in the Rough Habit Plate, before taking out a Class One race at the Gold Coast a fortnight ago. Punters clearly do not rate the runner from the Patinack stable as he is currently rated a $101 chance in the Derby.

From London will be ridden by Scott Galloway, taking the number of local riders in the 18 horse field to five.

John Sadler now needs to only sweat on one more scratching to ensure his talented gelding The Chevron gets a start in the Derby.

The Chevron has been well supported since Queensland Derby markets opened, and is currently rated an $8.00 chance, despite the fact that he is not assured a place in the final field.
