For all the tremendous publicity Constitution Hill generated for racing on Friday night on his Flat debut, Nicky Henderson is aware he "could undo that in 10 seconds" if the worst happened at Cheltenham.

The Seven Barrows trainer on Saturday remained undecided on whether his superstar would stay on the Flat for an intriguing career on the level, or return to hurdles at Cheltenham, having fallen in three of his last four starts over obstacles.
