Willie Mullins has confirmed the death of three-time Cheltenham Festival winner Vautour following what the trainer described as a "freak accident".
The seven-year-old gelding, who raced to victory in each of the last three years at Cheltenham, had to be put down after breaking a leg.
Mullins told the Racing Post on Sunday: "He broke a foreleg and has had to be put down. It's very tough to take for all of us.
"Vautour was out in a paddock with another of our horses, Shaneshill - the two of them go out to the same paddock most days.
"We don't know what exactly happened - it must have been a freak accident - but when one of the girls went out to feed the horses Vautour was found with a broken front leg and our vet had no option but to put him down."
