Eamonn Sheehy is still hoping to find a reason to explain Justified's disappointing run at Leopardstown in the In the Baileys Arkle Perpetual Cup.
The seven-year-old scoped clean after finishing third in the race and has had a blood test this morning.
The trainer had expected a better performance from Justified,
who had been unbeaten in all his three previous completed outings over fences.
"He scoped well after the race, we have taken blood from him this morning and are just waiting on the result of that," said Sheehy.
"I can't find anything wrong with him but obviously it wasn't his true run with Arteea on his form before.
"I hope I find something wrong because it would be kind of disappointing if I didn't.
"What we do with him next depends on what the results are. We may have to go to Navan now for the Flyingbolt Novice Chase (on February 19) and see if it was just a blip or what.
"If it doesn't go right at Navan then we'd probably have to skip the Arkle at Cheltenham. If he gets back on track at Navan then it would be the Arkle.
Justified has been pushed out from around 7-1 to twice those odds in places with the leading bookmakers for the Irish Independent Arkle Trophy at the Festival on March 14.
