Mikael D'haguenet has been ruled out of the Cheltenham Festival and being found "stiff and sore" following his schooling session at Leopardstown at the weekend.
The Willie Mullins-trained six year old had been a top priced 25-1 shot for the Arkle and 14-1 for the RSA.
Mullins this afternoon told the Racing Post: "Mikael D'Haguenet has been a bit stiff and sore following his schooling session at Leopardstown on Sunday and it has been decided that he won't be going to Cheltenham.
"While we were happy enough with the way he jumped at Leopardstown, it was his second racecourse school in the space of a few days and he did not come out of it as well as we had hoped.
"There are no plans yet and whether he will run this season, maybe at Fairyhouse and/or Punchestown, or will be kept until next season, is a decision we will make in the next few weeks."
