Daryl Jacob's replacement on Kauto Stone in the William Hill King George VI Chase at Kempton on Boxing Day has still to be decided.
Jacob won the JNWine.com Champion Chase at Down Royal on Kauto Star's half-brother, but a suspension picked up at Wincanton for mistaking the winning line has ruled him out of the potentially lucrative festive period and Charlie Liverton, racing manager to owner Robin Geffen, stated that as yet things are still up in the air.
He said: "Nothing has been finalised yet. Mr (Robin) Geffen (owner) and Paul Nicholls still need to sit down and come to a decision. We are just keeping our cards dry at present."
He added: "He's very much on target for the race, though, and has been doing everything nicely since Down Royal, touch wood.
"Being there will just be a dream, but at this stage that's all it is as this game has a habit of bringing you back down to earth, as we found out on Saturday with Cristal Bonus when he had to be put down.
"He was just beginning to realise his potential and it's such a shame."
David Pipe is still aiming Grands Crus at the race.
The grey was a red-hot favourite for the Paddy Power Gold Cup on his seasonal reappearance but disappointed in heavy ground and has since had a wind operation.
Following a piece of work this morning, Pipe tweeted: "Grands Crus galloped this morning and I am pleased with his progress. Still hoping to make the King George at Kempton on Boxing Day."
