Racing NSW stewards have been informed that Clear Thinking has experienced a minor setback and will not be participating in The Kosciuszko (1200m) at Randwick on October 19.
The five-year-old mare, sired by Dubawi and trained by Paul Messara and Leah Gavranich, is unbeaten in her three career starts.
Her most recent victory was in a Class 3 Highway Handicap over 1200 metres at Randwick.
Before her withdrawal on Tuesday, she was considered one of the leading contenders with horse racing bookmakers for the race.
Meanwhile, Scone-based trainer Rodney Northam has also withdrawn his five-year-old gelding, Palazzo Prince, from the $2 million contest.
Palazzo Prince sustained an injury to his off-side shoulder during trackwork.
