Kieren Fallon should be freed up to ride Blue Maiden in Sunday's Etihad Airways Irish 1000 Guineas.
Trainer Charlie McBride has used the former champion jockey for ride work on his horses, although he lost out to Aidan O'Brien when Fallon deserted Audacity Of Hope for Viscount Nelson in the 2000 Guineas at Newmarket.
Fallon would have partnered Seta if she had been confirmed this weekend, while Ryan Moore is expected to be aboard another of his former rides in Music Show.
Mick Channon's Music Show was the first home in the group racing on the far side of the track in the English 1000, finishing sixth, three places ahead of Blue Maiden.
The pair were closer when first and second in the Nell Gwyn at Newmarket earlier in the season.
"Obviously she was drawn on the wrong side in the Guineas, and also Jamie Spencer thought the ground was a bit soft for her," said McBride.
"They are saying it might be good to firm at the Curragh on Sunday, that would be fine for us and hopefully we can get a better result.
"She has had an easy couple of weeks, but is very well.
"Music Show was first on the far side, we have got a few lengths to find and I would say she will take the beating."
Explaining the jockey situation, McBride continued: "We have pencilled in Kieren.
"I've spoken to his agent and he is very happy for Kieren to ride her so hopefully he will. He has ridden her work before."
Audacity Of Hope only beat a couple home in the 2000 Guineas and should be out again imminently.
McBride explained: "I am looking at running him in a conditions race at Sandown next Thursday and, if that goes well, maybe look at the Britannia at Royal Ascot."
Meanwhile, Frank Ennis believes Sebastian Flyte is not a complete no-hoper in Saturday's Abu Dhabi Irish 2000 Guineas.
The Observatory colt is a 100/1 chance in some quarters after finishing seventh to Noll Wallop in the Leopardstown 2,000 Guineas Trial.
However, Ennis felt the ground did not suit his horse, who had been runner-up in a Newmarket Group Three last autumn, and expects conditions at his local track to be more suitable.
"He needed the race badly. He couldn't travel on the ground in Leopardstown. He's in very good form now," said Ennis. "We'd be hoping to run into a place. He's a good, tough horse. He's genuine and he'll definitely get the mile well.
"It will be perfect ground and he should come home very well. And if he finished in the first four, I'd be over the moon. The money's paid so we might as well go."
Sebastian Flyte has nine lengths to find on Noll Wallop and will get the chance to gain his revenge as Tommy Stack's charge will also be in the line-up.
"He won well at Leopardstown and before that we had always viewed him more of a Derby horse, but he quickened up very well in that race so we decided to take our chance in the Guineas," Stack's son and assistant Fozzy said.
"You have to respect Canford Cliffs, Xtension and Fencing Master. They all ran well in Newmarket and they will be tough nuts to crack.
"Then you have Steinbeck, who's obviously a very promising horse. He comes into the reckoning now so it's going to be an interesting race."
Canford Cliffs is one of the market leaders and the Newmarket 2000 Guineas third came through his latest workout in tremendous style.
"He worked this morning and everyone walked away very happy," said his trainer Richard Hannon.
"(Jockey) Richard (Hughes) said he felt like he had come on since New-market -- he settled well and he showed a good turn of foot."
Paul Hensey, racecourse manager at the Curragh, reports the track to be in tip-top condition after welcome rain fell overnight.
"We had three millimetres of rain on Tuesday night. It was just what the doctor ordered," he said.
"The forecast is good for the next few days, so it's perfect. We should be on good ground or better for the weekend."
