Appearance will miss the Chipping Norton Stakes but trainer Guy Walter says a recurrence of the tying up problems she has suffered in the past is only minor.
Walter said the mare would be redirected to Canterbury Stakes (1300m) on March 15, a week after the Chipping Norton (1600m), the first Group One race of the Sydney carnival.
Appearance has stepped up to open weight-for-age company this campaign, claiming Group Two wins in the Expressway Stakes and the Apollo Stakes after missing most of the spring.
"It is only temporary. I'm just not 100 per cent happy with her," Walter said.
"She had a little bit of a tying up episode and it wouldn't be a good idea to be running her over 1600 metres this week.
"Instead she will go to the Canterbury Stakes a week later, the George Ryder, the Doncaster and then the Queen Of The Turf again."
Tying up is a condition which causes muscle pain and stiffness and needs to be treated with rest.
The Canterbury Stakes-Ryder-Doncaster Group One treble is also the program for Appearance's stablemates Streama and Toydini.
Streama and Toydini finished second and third behind Boban in a tight finish to the Epsom Handicap in the spring.
With Appearance out of the Chipping Norton, a race Walter won four times with Tie The Knot, the trainer's stakes runners on his home track will be Any Day Will Do in the Group Three Wiggle Stakes (1400m) and Oaks-bound filly Zanbagh in the Surround Stakes (1400m).
Any Day Will Do goes into the race off a third in the Group Three Triscay Stakes (1200m) while Zanbagh was the subject of a stewards' inquiry after her eye-catching run first-up in the Light Fingers Stakes (1200m).
Although critical of jockey Blake Shinn's lack of vigour at the 350m, after a review of the sectional times stewards agreed with Shinn the first part of the race was run at a faster than usual pace and Zanbagh would not have finished closer than her four lengths ninth behind Sweet Idea.
