Leading jockey Barry Geraghty is set to pick More Of That ahead of Cause Of Causes for the Grand National at Aintree on Saturday.
The pair lead four possible contenders for Geraghty’s boss, the racehorse owner JP McManus.
A final field of 40 runners will be named on Thursday morning.
More Of That was sixth in the Gold Cup, while Cause Of Causes won the Cross-Country Chase at last month’s Cheltenham Festival.
Geraghty, who won the National in 2003 on Monty’s Pass, returned to riding at the weekend after being sidelined since breaking six ribs and suffering a collapsed lung in a fall at Kempton at the end of February.
The Irishman faced a dilemma over his National ride but looks likely to opt for the Jonjo O’Neill-trained More Of That, leaving Jamie Codd to once again ride Cause Of Causes for Gordon Elliott.
“Barry is set to ride More Of That, with Jamie ready to ride Cause Of Causes, though Barry is obviously waiting until the end to see if anything should change,” Frank Berry, McManus’ racing manager, told the Irish Independent.
Vieux Lion Rouge, for David Pipe, and the Brian Ellison-trained Definitly Red head the betting for Saturday’s race at about 10-1, with More Of That and Cause Of Causes next at 12-1.
McManus also has Regal Encore and Pendra among a total of 70 entries remaining in the contest, with a maximum line-up of 40 announced at about 10:00 BST on Thursday
As it stands the 40th horse in the field is the Pipe-trained La Vaticane, one ahead of stablemate Doctor Harper.
Terminally ill five-year-old Bradley Lowery is to be given honorary 41st place in the National racecard.
Aintree first day highlights – Thursday
The three-day Grand National meeting begins on Thursday, with Cue Card expected to be among the main attractions.
Colin Tizzard’s popular chaser, who fell at the third-last fence for the second successive year in the Cheltenham Gold Cup in March, will bid to win the Betway Bowl (14:50 BST) again after succeeding 12 months ago.
The Paul Nicholls-trained Silviniaco Conti, winner in 2014 and 2015, could be among his rivals.
Champion hurdler Buveur D’Air heads entries for the Aintree Hurdle (15:25), alongside stablemate and Cheltenham runner-up My Tent Or Yours, with previous winners Jezki and The New One other possibles.
On The Fringe and Pacha Du Polder head contenders for the Foxhunters’ Chase over the Grand National fences.
Enda Bolger’s On The Fringe has won the last two renewals, but could only finish fourth behind the Nicholls-trained Pacha Du Polder at Cheltenham.
