Racing: Ascot Gold Cup winner Yeats will face seven rivals in Saturday's Irish Field St Leger at the Curragh.
Aidan O'Brien's charge followed up his Ascot win with an easy success at Goodwood and will be a short-priced favourite to notch the third Group One success of his career.
O'Brien has not declared Puerto Rico, who was also a late withdrawal from last weekend's St Leger at York.
John Oxx's five-year-old mare Kastoria will try her hand at Group One level for the first time after a string of impressive performances this year.
Howard Johnson has declared Yorkshire Cup winner Percussionist while 10-year-old The Whistling Teal is also set to make the journey across the Irish Sea along with Frank Sonata and Akarem.
The field is completed by David Wachman's Fracas and Luke Comer's Chimes At Midnight.
