Racing: King Of Kings has chip cut out and odds pushed out

Aidan O'Brien expects his top two-year-old King Of Kings to make a full recovery after the son of Sadler's Wells underwent a minor operation to remove a chip from his off-fore knee.

The problem came to light after the leading 2,000 Guineas fancy, winner of Sunday's National Stakes at the Curragh, was found to be slightly stiff after light exercise on Tuesday.

The colt has drifted from 8-1 to 10-1 in Coral's Guineas market, although Simon Clare, the firm's spokesman, said that the move had nothing to do with the surgery but was because of weight of money for his stablemate Second Empire, winner of the Prix des Chenes 13 days ago. Second Empire was cut from 8-1 to 7-1 joint-favourite with Daggers Drawn for the Classic.
