In an about-turn, Reisling Stakes winner French Fern will take her place in the Golden Slipper.
After her qualifying win on Saturday, trainer David Payne was reluctant to commit the filly to a start in the $3.5 million Golden Slipper on March 19.
But part-owner Wilf Mula has announced on Twitter she will run.
Mula is also part of the group that races second favourite Flying Artie, runner-up to his Mick Price-trained stablemate Extreme Choice in the Blue Diamond Stakes.
"... Today decided to run French Fern as well as Flying Artie #2runners ???? #yeh" Mula tweeted.
The Joe Pride-trained Kentucky Miss runs for Mula and his fellow owners in Saturday's Magic Night Stakes, one of the two races at Rosehill on Saturday guaranteeing the winner a Slipper berth.
