Flemenstar is likely to be given another chance over Leopardstown's three-mile course in the Hennessy Gold Cup following his brave third in the Lexus Chase.
After travelling keenly throughout, Peter Casey's seven-year-old hit the front two from home but tired on the run up to the line and was collared by Tidal Bay and First Lieutenant.
Casey said: "Andrew (Lynch) said he pulled too hard. Maybe it would have been better if he had gone off in front.
"I don't think it was too far for him today. He boiled over a little bit. We had a job putting a saddle on him and he wasn't settled.
"Andrew said we'll have to go for the Hennessy and you have to do what the jockey says."
Mouse Morris was thrilled with the performance of First Lieutenant, saying: "I was delighted with that. He won't go to the Hennessy. He'll have a break and will go straight to Cheltenham for the Gold Cup."
