Nicky Henderson, Altior’s trainer, has said that the horse will miss the Tingle Creek Chase at Sandown next month due to a “wind problem”.

Altior was favourite for the race before he was withdrawn and he will need to have a “small procedure” to rectify the problem.

In a statement Henderson said, “I’m really disappointed to report that Altior will miss the Grade One Tingle Creek at Sandown next month due to a wind problem that has surfaced, which means he will not be ready in time. He started faster work last week in the build-up to Sandown and did an excellent piece with Lough Derg Spirit last Tuesday. He was actually quite brilliant, and it is quite bizarre this has come up as up until now he had shown no signs whatsoever that there was anything untoward.”

She went on to say that two vets have concluded that the horse has an issue with his wind whereby his larynx isn’t opening enough. As a result, he will be undergoing a small procedure before returning to racing.

However, Henderson is optimistic that Altior will be able to recover in time for the Queen Mother Champion Chase at this season’s Festival.

She said, “Whether we are able to fit in a prep race we don’t know and only time will tell, I certainly wouldn’t want to speculate. We can have racecourse gallops if we need too, but Altior will have a month’s box rest and we’ll go from there.”

Henderson said that the situation is “tough” for everyone and that they have temporarily run out of luck, nonetheless, she took an optimistic view saying, “this horse doesn’t have to retire and he will be back, make no mistake about it.”
