Vicenzo victorious for Nicholls
Paul Nicholls was among the winners on Friday's undercard at Kempton as Vicenzio Mio won the opener on the card as an even money favourite.
"He's still a colt and has been very stuffy, but that looked a smart performance," said Nicholls.
Vicenzo Mio was cut to 20-1 from 33s by the race sponsors for the Triumph Hurdle but is now only 16-1 with Coral.
"He'll get a trip and the only question about the Triumph is that he seems to like soft ground," Nicholls said.
"But if he keeps progressing, you never know. I suppose he could run somewhere like at Cheltenham at the end of January."
Mickie is one of the toughest around and the 5-2 favourite slugged out the William Hill - Download The App Mares' Handicap Hurdle.
Henry Daly's grey stayed on well to score at Newbury, and although she surged into the lead on the turn for home, she eventually had to fight hard to beat Cannon Fodder a length.
Jockey Richard Johnson said: "She hasn't got too many gears but she was fit, and she was tough. Hopefully the handicapper won't be too hard on her now."
On a day Henderson will choose to forget after the setback incurred by Sprinter Sacre in the feature, it would have been cold comfort to see Ma Filleule (13-2) winning the following event, the William Hill - Bet On The Move Handicap Chase.
Nicholls was denied a three-timer when John Ferguson's Three Kingdoms short-headed Vibrato Valtat in the William Hill - In The App Store Handicap Hurdle.
