Two-time Queen Mother Champion Chase winner Altior is reported to be in a stable but critical condition after suffering a severe bout of colic.
A true jump racing great, Altior won 19 races in a row for Nicky Henderson, including the 2018 and 2019 Champion Chase, on his way to becoming the highest-rated horse in training, with a peak mark of 175.
He was retired in 2021 aged 11, bowing out having won 21 of his 26 career starts, including 10 Grade One races and four victories at the Cheltenham Festival.
