The Tullow Tank was found to be suffering from an inflammatory lung infection after his below-par display in the Drinmore Novice Chase at Fairyhouse.
Sent off the 7-4 favourite for the best renewal of the Grade One in many years, the Sandra Hughes-trained six-year-old could finish only fifth behind Valseur Lido and was subsequently sent for tests.
"We've got the results back and he was suffering from an inflammatory lung infection," said owner Barry Connell.
"That would also probably account for the elevated heart rate he had.
"He's obviously picked it up somewhere, but it's nothing serious.
"We'd hope to get him back on the track fairly soon, but it's too early to say whether or not he'll be running at Christmas (Topaz Novice Chase, Leopardstown)."
