Rob Hornby has confirmed he will reunite with Irish Derby hero Westover at next Sunday’s Prix de l’Arc de Triomphe at ParisLongchamp.
He will succeed Colin Keane, who won the Irish Derby aboard the colt trained by Ralph Beckett.
Hornby partnered the homebred owned by Juddmonte when he won the Sandown Classic Trial and then finished third at Desert Crown in the Derby.
However, Irish champion jockey Keane replaced him at the Curragh before finishing fifth in the King George VI and Queen Elizabeth Stakes.
“It was confirmed last night that I will be riding him in the Arc which is hugely exciting and I can’t wait to get back on him,” Hornby revealed on Luck on Sunday.
“He’s in great shape, I’ve ridden him in his last four jobs and he looks good.”
Westover, a son of Frankel, has won three of his seven starts and the bookmakers are shooting him 16-1 overall for the Arc, with Luxembourg formed by Aidan O’Brien the market leader at 4-1.
