Racing: Cells tell story of Sil Sila

Sil Sila, who disappointed so badly when among the fancied runners for Wednesday's Yorkshire Oaks, has been found to have had an abnormal count of white blood cells. The filly, previously winner of the Prix de Diane (French Oaks), underwent extensive tests after being virtually tailed- off in the Group One event at York.

"Sil Sila has a mild infection and things have probably been worsened by the journey up to York and all the hurly burly," her trainer, Bryan Smart, said.

"We are hoping that it's not a long-term problem and that she will be able to return soon. The Prix Vermeille will come too soon but there are plenty of other options for her towards the end of the month."

Other possible targets include the Sun Chariot Stakes at Newmarket, Ascot's Princess Royal Stakes and a Group One event in Italy.
