Last year’s Champion Hurdle winner Constitution Hill has been ruled out of the Cheltenham Festival.
The seven-year-old had a poor workout at Kempton Park last week which led to medical checks.
Trainer Nicky Henderson said at the time the horse was unwell and struggling with a build up of mucus, but hopefully would recover in time.
But results from a blood test were “quite a way from being satisfactory” and he is not fit to run.
“Very sadly we are going to have to admit defeat in the battle to get Constitution Hill ready for the Champion Hurdle,” Henderson said on X.
“We therefore have to declare that he will not be running there this year.
“He has undoubtedly improved over the weekend and seems noticeably brighter than he was at the end of last week, and I really did think he was much perkier when ridden this morning.”
Henderson added that the “significant markers” on the blood test had come down since last Thursday but still indicate that the horse has not fully recovered from the illness.
He also said that they would not add further stress to the horse in order to ensure his improvement.
“This is very sad for all of us but it is in everybody’s best interests that we have a fit and healthy Constitution Hill to win back his crown next year,” the statement continued.
AP McCoy called Constitution Hill “the horse of a generation” after last year’s win but he has only raced once this season.
That came in the Christmas Hurdle at Kempton on Boxing Day where he won easily under jockey Nico de Boinville, but he missed last month’s Cheltenham Trials Day over fitness concerns.
The Cheltenham Festival starts on Tuesday 12 March.
Analysis – ‘There will be other days’
Frank Keogh, BBC racing reporter
Racing’s big will-he, won’t-he wait is over and it’s bad news for fans of the sport that Constitution Hill will miss its showpiece meeting next week.
After pulverising the opposition last year, his defence of the Champion Hurdle was keenly awaited, particularly as he has only raced twice since.
It will inevitably take some of the gloss off the meeting’s opening day next Tuesday, and now last year’s runner-up State Man is odds-on favourite to triumph for dominant Irish trainer Willie Mullins.
Constitution Hill’s trainer Nicky Henderson has put the welfare of his horse first and kept punters well briefed on the situation.
There will be other days for this exceptional equine star.
