Glamour filly Autumn Glow is injured and will miss Saturday’s Group 1 Flight Stakes at Randwick.

Trainer Chris Waller broke the news on Friday morning, revealing that the undefeated daughter of The Autumn Sun was suffering from a leg injury that requires surgery.

“Unfortunately, Autumn Glow was found to be slightly lame this morning in her right front leg,” Waller said.

“An x-ray was taken, which shows a minor chip in her right front knee. She will therefore not take her place tomorrow in the Flight Stakes.

“The chip will be surgically removed, giving her the best possible prognosis for a return in the autumn.

“This is very disappointing for all involved, particularly the horse. She is a very exciting prospect and we are confident that she will make a full recovery.”

Prior to her withdrawal, Autumn Glow – the $1.8m sale-topper from last year’s Inglis Easter Yearling Sale – was the $1.50 favourite for the $750,000 Flight Stakes (1600m), which was to be her fourth start.

Her withdrawal leaves Autumn Glow’s stablemate Lady Shenandoah in a battle for favouritism with Snow In May, who was runner-up to Autumn Glow in the Group 2 Tea Rose Stakes on September 21.
