China Rock could be back in action at the end of next month in the Lexus Chase at Leopardstown.
The Mouse Morris-trained eight-year-old has not been seen since the Cheltenham Gold Cup in March when he was forced to pull up before the second-last fence.
He was suffering from tendonitis and remained in England for stem-cell treatment, a procedure Morris' 2006 Gold Cup winner War Of Attrition also underwent.
"He's good and we're training him for the Lexus," said Morris.
"He had stem-cell treatment, just like War Of Attrition did.
"He's been back cantering for quite some time so it hasn't taken him as long as War to get back.
"He was in the process of running a massive race in the Gold Cup and I'm not sure if it happened coming down the hill, but he was still bang there three-out.
"Fingers crossed, he'll be back soon and if he doesn't make the Lexus, it will be the Irish Hennessy.
"He's a good ground horse so I wouldn't want him starting back on heavy.
