Owner Rick Porter announced that his champion was suffering from a fever.

“Unfortunately we have to report that Songbird will miss the Kentucky Oaks,” Porter said via his Fox Hill Farms Facebook page.

“She developed a low grade fever after the Santa Anita Oaks and has not been able to go out to the track.”

Porter said Songbird had started on a course of antibiotics and as a result it will be seven to 10 days before she can return to the track.

“We are sorry to have to miss the Oaks, but what’s most important is to get Songbird well, and we have two great vets along with Jerry Hollendorfer and his team taking good care of her.”

Last year’s dominant G1 Breeders’ Cup Juvenile Fillies winner picked up where she left off this season with facile victories in the G2 Las Virgenes Stakes, G3 Santa Ysabel Stakes and G1 Santa Anita Oaks at her last outing on April 9.
