A run for fancied irish challenger Whinstone Boy,as short as 18/1 with Bet365 for the John Smith's Grand National, is still very much in the balance.
Alloted 10s 4lb in the 4m 4f contest, the nine year old needs at least three horses to drop out in order to make the cut on Saturday.
With good to soft going anticipated for the Aintree showpiece Whinstone Boy has come in for strong support recently, and is currently a best price 25/1 with sportingbet and William Hill.
Winner of the Thyestes Chase at Gowran Park in January the James Mangan trained gelding will relish testing conditions,and off a featherweight is sure to be well backed at the weekend, if fortunate enough to creep into the race.
With 10 horses dropping out at the latest confirmation stage two that are now guaranteed a run are the David Pipe trained The Package and Hello Bud, winner of the 2009 Scottish Grand National.
At the bottom of the handicap there are five horses currently on 10s 5lb, but official BHA ratings mean the two that would currently make the final field are Flintoff ( a non-runner in today's Irish Grand National ) and Abbeybraney.
The Packages' conqueror in Cheltenham's William Hill Trophy, Chief Dan George, looks highly unlikely to get in the race off 10s 2lb and may have to wait a week,with Ayr's Scottish equivalent as the logical alternative.
