Racing: Aidan O'Brien's Chenchikova could miss the Vodafone Oaks at Epsom on June 2nd after suffering a setback.

The filly, who is a full sister to 2002 Derby hero High Chaparral, made a favourable impression when winning on her debut at Tipperary last September.

However, she disappointed at the Curragh on her seasonal bow when only fourth in a Group Three ran on heavy ground and O'Brien has warned she may not be ready for the Classic.

"She has suffered a minor setback and it's possible she may not make the Oaks," said a spokesman for owners Coolmore.
