Davy Russell will not be able to make his return from injury at Clonmel today due to a problem with "paperwork".
The dual champion jumps jockey had three booked rides, including Mallowney in the feature Clonmel Oil Chase. He said: "I'm just a bit unlucky. It's paperwork, which is unfortunate.
"Hopefully it will be sorted out before or after the weekend. I don't know yet when I'll be able to comeback but it won't be long."
Russell has been sidelined since he suffered a broken arm and a broken foot in a fall at Cork on 30 August.
