Gigginstown House Stud insists no decision on Davy Russell's replacement as its retained jockey has yet been made despite speculation Bryan Cooper will get the job.

Cooper is rated a 1-5 chance by Paddy Power to take over the top spot at Gigginstown, but the young rider declined to comment when asked before racing at Fairyhouse on New Year's Day.

Gigginstown's racing manager Eddie O'Leary revealed his brother Michael's operation is yet to firm up a successor.

"We haven't decided anything. We're talking to a few and there's no news yet. When we know, you'll know," he said on Wednesday afternoon.

Since Russell was informed by Michael O'Leary at Punchestown on New Year's Eve he would no longer be the official No.1 to Ireland's champion owners after seven years in the job, Cooper has been strongly linked with the role.
