Stan James cut Mille Chief from 7/1 to 5s for the Triumph in light of Pistolet Noir's (20 from 8) shock defeat at the hands of outsider Baccalauerate who taught his rivals a lesson in the Finesse Hurdle.
Paul Nicholls was not too disheartened with Pistolet Noir's performance and it is still likely he will be entered for the Triumph.
"It was a surprise to me that he was made the favourite for the Triumph because he's not run on the Flat," he said.
"He was quite clueless when we got him and he wants two and a half miles.
"We will probably still put him in the Triumph but we might give him another run first and see how he gets on."
