Realt Dubh is set to make his seasonal reappearance at Naas at the end of the month after trainer Noel Meade decided against running him at Limerick over the weekend.
Last season's Powers Gold Cup winner had been in line to return to action in the PricewaterhouseCoopers Chase won by West With The Wind, but Meade decided against it after seeing his charge work during the week.
"I worked him last week and I just thought he was a bit of work short, so I decided not to run him," said Meade.
"He's in good form and I'm happy with him but he was a bit tired after work on Thursday and I felt he hadn't enough work done, so we'll give him another week.
"I'd say he'll run in the Poplar Square Chase at Naas (October 29) now."
Muirhead's victory in Sunday's Munster National rounded off a fine couple of days for the trainer having completed a hat-trick of maiden hurdle wins with Leceile, Dylan Ross and Texas Jack at Fairyhouse on Saturday.
Meade said: "All three won well, including the mare (Leceile), although she had been beaten the time before.
"Texas Jack is a nice horse. He won his bumper at Punchestown in the spring and it was a good performance for him to win first time over hurdles as he's still quite weak. He'll be very good when he gets a bit stronger.
"Dylan Ross is a horse I've always really liked and he won two bumpers and would have won over hurdles at Down Royal last Christmas but for falling at the last. Then he injured a knee and had a bit of a wind problem but he's a very nice horse and I hope there's plenty to look forward to."
"I don't have any real plans for any of them but you'd like to think they might be up to running in some of the better novice hurdles somewhere down the line."
