Diamond Harry will have a new jockey for the first time when he makes his debut over fences at Haydock on Saturday.
Connections of the talented seven-year-old are on the lookout for a replacement to regular partner Timmy Murphy in the sportingbet.com Altcar Novices' Chase.
Murphy, who has ridden the horse in all his nine races to date, is set to be at Ascot and claimed by owner David Johnson.
His mounts at the Berkshire venue are likely to include Well Chief, trained by David Pipe, in the feature Victor Chandler Chase.
"It looks like we'll be needing a new jockey. Everybody has been getting exciting about it and that's why my phone has been so busy," said trainer Nick Williams.
"I haven't spoken to the owner about it yet, but we've had some offers already.
"He definitely runs, he's in good form and he jumps well at home."
Owner Paul Duffy is excited about Diamond Harry switching from hurdles to fences at the Merseyside track, where he might clash with the classy Punchestowns from Nicky Henderson's stable.
"We are aiming for chase career now. That has always been the objective and he is built like a chaser," said Duffy.
Punchestowns may well be in opposition following a workout on Tuesday morning.
Venetia Williams has raised the possibility of Mon Mome running in the totesport Cheltenham Gold Cup ahead of the defence of his John Smith's Grand National crown on April 10.
The shock 100/1 winner of last year's Aintree highlight will have his third outing of the campaign in the Peter Marsh Chase at Haydock this weekend, after which the blue riband is a possibility.
Williams said: "There is every chance he may join Miko De Beauchene in the Blue Square Gold Cup at Haydock next month.
"He will also have an entry in the Cheltenham Gold Cup. That isn't a target as such, but it is an option."
Williams was delighted to welcome back the Paul Beck-owned trio of Stan, Flintoff and Atouchbetweenacara to her yard after a brief spell in South Wales with Tim Vaughan.
The three horses all failed to fire in their respective starts for Vaughan and returned home to Herefordshire a little under two weeks ago.
Williams said: "I was pleased to welcome them back but we haven't had the chance to determine much with them since their return."
Connections of Zaynar are hoping lightning can strike twice with According in this season's Triumph Hurdle.
He has gone into training with Nicky Henderson, but time is beginning to run out before his big target.
"He's obviously been showing up very well at home which is why he's towards the head of the betting for the Triumph. The only concern is that we are beginning to run out of time because he'd need two runs before the Triumph."
Cloudy Lane will bid for back-to-back successes in the Grade Two Peter Marsh Chase at Haydock on Saturday. The 10-year-old won the valuable prize by just a head 12 months ago and is now 2lb higher in the handicap.
