Constitution Hill to be rescoped on Friday as Champion Hurdle defence in major doubt

"Unfortunately, in a routine gallop this morning, Constitution Hill was very disappointing and it transpires, after the vet has scoped him, that there is evidence of mucus," said Nicky Henderson.

Nicky Henderson is not giving up hope of Constitution Hill being able to defend his Unibet Champion Hurdle crown and will have his unbeaten superstar "rescoped" again on Friday, after a below-par workout at Kempton Park on Tuesday put his participation in doubt.

As has become tradition, Henderson took several of his Festival contenders for a spin at the Sunbury circuit, including Constitution Hill, whose only start this season was in the Christmas Hurdle at Kempton on St Stephen's Day.
