Saturday's OLBG.com Mares' Hurdle has been brought forward which could allow Ruby Walsh to ride at Doncaster and Cheltenham.
The unbeaten Annie Power had been entered in the Grade Two contest and trainer Willie Mullins has confirmed that she will take her chance as he looks to provide her with more experience over hurdles.
Mullins has increased the number of runners that he has had in Britain this season and he could also be represented by Boston Bob in the galliardhomes.com Cleeve Hurdle at Cheltenham on the same afternoon.
The nine-year-old had been entered for the John Mulhern Galmoy Hurdle at Gowran Park on Thursday but connections have opted to bypass that contest, leading to suggestions that he could run at Cheltenham on Saturday where he would have to take on Big Buck's and Reve De Sivola.
The Mares' Hurdle had originally been scheduled to be run at 14.40 which would have left Ruby Walsh (should he opt to ride in England rather than at Leopardstown) insufficient time to head south to Cheltenham to ride in the Cleeve Hurdle.
However, the race has been moved in the running order to go off at 14.05 which opens up the tantalising possibility of Walsh, the jockey who knows Big Buck's better than anyone else, being at Cheltenham to take on the great stayer on his return from injury.
"We've swapped the race times around with the Albert Bartlett as there's a better chance of her turning up," said Lucy Rhodes, Doncaster's media and communications executive.
"It's fantastic that such a great horse like Annie Power is coming over and ticket sales have been gathering momentum since she received an entry. It's very exciting."
