Charlie Longsdon is waiting on the availability of Paddy Brennan before committing Hidden Keel to a run in Saturday's totepool Challengers Novices' Chase at Sandown.
The grey opened his account over fences in impressive style at Leicester a month ago and his trainer is keen to test the water in this weekend's Grade One event, better known as the Scilly Isles Novices' Chase.
However, if Brennan is unavailable due to other commitments, it is unlikely he will be allowed to line up.
"He may take his chance, a lot depends on whether we can get Paddy Brennan to ride him," said Longsdon.
"He's stepping up in grade and Paddy knows the horse inside out. I originally thought he would be unable to ride but Khyber Kim is not in the Welsh Champion Hurdle as I thought he might be, so hopefully he can ride.
"The horse is still a baby and I don't want to put a jockey that has never ridden him before to ride on Saturday. We should find out about Paddy in the next 24 hours.
"I would like to run the horse. It's a step up for him but he's done everything right over fences so far.
"We thought he was quite well handicapped over hurdles at Cheltenham back in November and he got beaten 18 lengths by Grands Crus. He looks a machine though, so there was no disgrace in that.
"We were actually giving Grand Crus weight that day and I think that run shows our horse is entitled to be running in decent races.
"We'll see how he goes on Saturday, if he runs, before we make a decision on going to Cheltenham."
