Nolan is convinced there is something ailing his 2010 Irish Hennessy hero after he finished a well-beaten third to Quito De La Roque in the Kinloch Brae Chase at Thurles on Thursday.

"There is something catching him and he's not finishing his races," said the County Wexford handler.

"I wish he would gallop a bit more at the end of his races, but in his last couple of runs he's not galloping to the line.

"There's a physical issue and hopefully we will find it and there should still be a couple of races in him.

"I don't think it's all over yet with him - hopefully we'll get him back to his best form.

"There is some little thing catching him. We don't know what it is but it could be making a bit of a difference.

"He's putting in more mistakes than he used to do.

"Hopefully we can find something out there and iron out the problems and get those jumping errors to disappear."
