Paul Nicholls has revealed Big Buck's could reappear at Haydock on Betfair Chase Day while Aaim To Prosper has also joined the champion trainer's Ditcheat team.
The former, unbeaten in his last 17 races over hurdles, was expected to make his traditional reappearance at Newbury's Henenssy meeting.
However writing in his exclusive column at www.betfair.com/paulnicholls the trainer said: "Big Buck's has been given an entry in the Betfair Fixed Brush Handicap Hurdle on Betfair Chase Day. It is a very valuable race, worth more than the Newbury race that is normally his reappearance, but money isn't everything and we will do what is best for the horse.
"But, at this stage, Haydock is only a tentative entry for him, so don't get carried away yet."
Of his new recruit from the Flat, the trainer added: "Big Buck's may well have some competition from this yard this season, as Aaim To Prosper has joined us to go hurdling!
"He became the first horse to complete back-to-back Cesarewitch wins last month and, at 112, must be one of the highest-rated Flat horses to have joined us from that sphere, maybe similar to Celestial Halo in ratings terms.
"The owners have Sidney Melbourne and Shooters Wood with me, and have kindly sent me him. He clearly is an exciting hurdling prospect."
