The Nicky Henderson-trained seven-year-old made a fine start to his chasing career when winning in some style at Kempton in November, but things have not gone to plan since.
He went to Sandown for the Henry VIII Novices' Chase after Kempton but unseated at the last when looking held by Sceau Royal, and then fell in the Clarence House Chase at Ascot won by Un De Sceaux.
As short as 10-1 with some firms, the Michael Buckley-owned gelding is a best-priced 16-1 for the Racing Post Arkle Trophy Novices' Chase.
Henderson said: "He has had his palate cauterized.
"We put him in the Arkle. He will be back for that and he should be fine."
Meanwhile, David Pipe has warned Grade One winner Moon Racer faces a race against time to be ready for the Betfair Hurdle at Newbury on February 10.
The 2015 Champion Bumper hero has not been seen since finishing sixth in a Grade One at Aintree in April, after suffering a bout of colic in the summer.
Pipe said: "Moon Racer is still going well at present. He is in the Betfair, whether he will be ready for that will be down to the wire. He is looking well, though."
He added: "The trouble is he is nine now and we all get a bit slower with age, most of us do anyway."
