Oscars Well is said to be "sound but sore" following his heavy fall at Punchestown on Sunday.
The Grade One-winning hurdler was sent off 8-15 favourite to win for a second time over fences but took a nasty tumble at the second obstacle in the Craddockstown Novice Chase won by Twinlight.
Oscars Well managed to get out of the racecourse and onto a road briefly before being caught.
"It was the fall that made him sore, it was a hell of a fall." - Harrington
"He's sound but he's a bit sore. It was the fall that made him sore, it was a hell of a fall," said his trainer Jessica Harrington.
"He took off onto the road as well but it was just the fall that made him very sore.
"We'll leave him this week and see how he is before thinking what to do with him next."
