The nine-year-old looked to have the world at his feet a couple of years ago after winning three Grade Ones over fences, after which he finished placed in the Lexus Chase and the Hennessy Gold Cup at Leopardstown.
However, after a disappointing run at Aintree in April of last year, he moved from Peter Casey’s yard to the Tony Martin stables.
Although Flemenstar made a winning debut for his new trainer in the Fortria Chase at Navan last November, he has not been seen since.
Owner Stephen Curran hopes he could be back on the racecourse early next year.
Curran said: “He’s been back in work around four months. He had seven weeks walking on the road and six weeks trotting and he looks in great order.
“He’s going to go back to Anglesey Lodge Hospital up in the Curragh in the first week in December for another scan and that will tell us a lot more.”
