A total of 13 fillies have been left in the Investec Oaks at Epsom on Friday at the latest forfeit stage.
They include the William Haggas-trained Sea Of Class, an impressive winner at Newbury last weekend on just her second start.
The Sea The Stars filly was presumed an unlikely runner, but the defection of ante-post favourite Lah Ti Dar means the Classic now has an open look to it. Haggas can also call on Musidora Stakes winner Give And Take.
Speaking to ITV Racing, Haggas said of Sea Of Class: “I don’t know, really. She’s a bit inexperienced, but the favourite coming out makes you wonder, so I think it is very possible she might run.
“We’ve said we’ll decide on Wednesday morning and that’s what we’re going to do.”
Charlie Appleby’s Wild Illusion is the only Group One winner still in the race, courtesy of her victory in the Prix Marcel Boussac last year.
Aidan O’Brien is responsible for eight of the possibles, with Magic Wand, Forever Together and Bye Bye Baby among his team.
Clive Cox’s impressive Lingfield winner Perfect Clarity and David Simcock’s Ejtyah are also engaged.
In the Investec Coronation Cup, Cracksman will face a maximum of seven rivals, but among those is Cliffs Of Moher, declared to run at the Curragh on Sunday.
O’Brien is likely to be represented by Idaho, with Yucatan also left in.
Hawkbill for Charlie Appleby, Roger Varian’s Barsanti, Sylvester Kirk’s Salouen and Windstoss from Germany complete the list.
