The post-mortem results have returned following the death of Grand National horse Celebre D'Allen who collapsed after the race before dying two days later.

It concludes that the exercise-associated episode which led him to collapse after jumping the last in Saturday's Randox Grand National had ceased to be a factor by the time he died.

Instead the horse died of complications linked to pleuropneumonia (a lung infection).

Blood tests taken on the day of the race showed no presence of the virus and thus vets believe it is not possible to separate the emergence of the secondary problem from his run at Aintree on Saturday. 

A statement from the BHA said: "The findings of the post-mortem state that the exercise-associated episode experienced by the horse after the race had concluded by the time of death. 

"However, a severe bacterial respiratory infection [pleuropneumonia] had occurred post-race which led to the horse’s deterioration on Monday evening, with the subsequent onset of sepsis or endotoxaemia [the release of harmful substances into the bloodstream from bacteria] likely to have been a key factor in the cause of death.

"Blood tests taken from the day of the race indicate that the infection had not been present in the horse on raceday, and was therefore developed after the race."

The statement continued: "Further bloods taken on the Monday indicated a severely compromised immune system. These indications had not been present in the bloods taken on the day of the race. This indicates that this issue emerged subsequent to the race and the exercise-associated episode.

"The heart pathology found no issues which are likely to be significant in the death of the horse."

Celebre D'Allen led the Grand National field towards the 29th of the 30 fences alongside third-placed Grangeclare West before fading on the run to the last. 

Jockey Micheal Nolan dismounted from the 13-year-old after jumping the last and Celebre D'Allen collapsed several moments later. 

The horse received extensive treatment on track alongside Broadway Boy who suffered a horrific fall at the 25th.

Nolan received a ten day ban after a stewards enquiry found him guilty of "continuing in the race when the horse appeared to have no more to give and was clearly losing ground after the second-last fence".

Celebre d'Allen, the horse who collapsed on the course at Aintree following the Grand National has died.

The rest of the day's racing was delayed after Celebre d'Allen, who was pulled up by jockey Michael Nolan and Broadway Boy who took a nasty fall at the 25th hurdle both, required treatment on the track.

Trained by Philip Hobbs and Johnson White, the 13-year-old horse collapsed but walked into the horse ambulance later that day.

Nolan was then subjected to a 10-day ban after an investigation concluded that he continued to ride the horse that had 'no more left to give'.

A report from the stewards revealed: "An inquiry was held to consider whether Micheal Nolan, the rider of Celebre d'Allen, had continued in the race when the horse appeared to have no more to give and was clearly losing ground after the second-last fence.

"The rider and the veterinary officer were interviewed, and recordings of the incident were viewed. The rider was suspended for 10 days."

Today it was revealed that the horse has now died despite the best efforts of the vets.

The horse's owners, Philip Hobbs & Johnson White Racing, shared a short statement on X alongside a broken heart emoji. They said: "We're heartbroken to share that Celebre D’Allen has passed away. He received the very best treatment by the veterinary teams and was improving.

"However, he deteriorated significantly last night and could not be saved. He was a wonderful horse and we will all miss him greatly."

Aintree Racecourse also released a short statement. A spokesperson said: "Celebre D'Allen was a much loved member of Philip and Johnson's team and all of us at Aintree are deeply saddened by today's news.

"Those who look after British racing's equine athletes every day have a unique bond with their horses and provide the very best care imaginable. Our thoughts are with everyone connected with Celebre D'Allen."

The British Horse Racing Authority (BHA) has a fatality review process for when race horses die.

BHA say more than £50million has been invested into advancing equine health, veterinary science and research since the year 2000.

BHA released a statement after the race on Saturday, saying: "Both horses received immediate and extensive treatment by the vets, also calling on the first class facilities and various teams on site. This treatment and assessment will continue into the evening."

Irish jockey Micheál Nolan has been given a ten-day suspension after continuing to ride his horse, Celebre D'Allen, during the Grand National, when the horse had 'no more to give'.

The horse was one of two to fall, along with Broadway Boy, and was tended to by vets before being brought back to the stables.

A statement said: “An enquiry was held to consider whether Micheal Nolan, the rider of Celebre D'Allen, had continued in the race when the horse appeared to have no more to give and was clearly losing ground after the second-last fence.

“The rider and the Veterinary Officer were interviewed, and recordings of the incident were viewed. The rider was suspended for 10 days.”

With Patrick Mullins victorious in yesterday's Grand National aboard Nick Rockett, it means that he joined his cousins David and Emmett Mullins in winning the sport's most iconic race.

David won with Rule The World 2016, and Emmet won on Noble Yeats in 2022.

That leaves cousin Danny Mullins, who came fifth yesterday on Meetingofthewaters, as the odd one out.

After the race, Patrick couldn't resist a sly dig at his cousing.

Speaking with ITV, he said: "It's everything I dreamed about since I was a kid. It's a cliche, but when I was 5 or 6 years old I remember reading books about the National. So to put my name there is really special.

"The most important thing is that David and Emmet have already won it. So I had to level with them. So poor Danny has to get his finger out now!

"He's fine. I wouldn't mind going for a warm bath myself. It's just a brilliant horse. He's not very big. He's one of the smallest in the field. He's 50 or 60 kilos lighter than the rest of the National horses today, but he's brave as a lion."

Racing fans have rejoiced after it was confirmed that Broadway Boy has walked off the Grand National course and into a horse ambulance after what looked like a horror fall.

The horse fell at the 22nd fence when he was out in front, with fans calling it one of the worst falls they'd ever seen.

After the final two races were delayed while he received treatment on the course, it was confirmed he was up and walking as he was taken back to the stable for further assessment.

Jockey Tom Bellamy has been taken to Aintree University Hospital for further assessment.

though he is not out of the woods yet, the fact he is up and walking about is a positive sign for the horse.

The final two races of the Grand National Festival at Aintree have been delayed as Broadway Boy continues to be assessed on course.

The race was eventually won by trainer Willie Mullins and his son Patrick on board Nick Rockett.

Five of the top seven horses in the Grand National were trained by Irish trainer Willie Mullins, including the winner, Nick Rockett.

The 33/1 outsider won the 2025 Grand National with Mullins son Patrick on board and was overcome with emotion in the winners enclosure.

He said, through the tears: "It's lovely to be able to give your son a ride in the National, but for him to be able to win it... unbelievable."

Mullins trained horse took the top three spots as well as fifth and seventh. I Am Maximus was second followed by Grangeclare West.

Nick Rockett has won the 2025 Randox Grand National.

The race got underway from a standing start and all 34 runners took the first safely. Duffle Coat was the first to unseat the rider at the third.

The experts top tip, Perceval Legallois who went out second favourite was the first big name to go, falling with two thirds of the race still to go.

I Am Maximus, the favourite who looked to win back-to-back Grand Nationals, stuck close to the rail as he did last year, Paul Townend running an almost identical race.

Broadway Boy was leading by two lengths but made a bad mistake in the closing stages and fell.

But the day belonged to outsider Nick Rockett, ridden by amateur jockey Patrick Mullins, son of trainer Willie who won the 177th edition of the prestigious race.

Grangeclare West came home in third, giving Willie Mullins an incredible 1-3.

A Welsh jockey who is allergic to horses is hoping to win this year's Grand National.

Sean Bowen rides the 25/1 outsider Three Card Brag in the 4pm as he looks to achieve a childhood dream.

The 27-year-old currently leads the jockey's championship - awarded to the rider with the most wins over the course of the year.

He looks unbeatable with just one month left of the season. 

Back in February he rode his 1000th winner which is remarkable given he is allergic to the animals he spends his life around.

Speaking to BBC Sport he said: "I still am (allergic to horses) now a little bit, it's a bit of a weird one.

"If dad would come in from clipping and there'd be horse hair everywhere, I'd be itching for days. Even now, sometimes if I spend all morning round horses, I'd be sneezing for the rest of the day."

His parents, Peter and Karen have been training racehorses for 30 years.

He continued: "I can't say I grew up loving it. I enjoyed football until I was around 11. I started riding when I was about 10.

"I suppose both my brothers got into riding ponies, and then I had no-one to play football with, so I had to get on the ponies instead."

Despite his initial reluctance, winning the Grand National has long since been his dream.

"I’ve dreamed of winning since I was a young boy, it’s the one race everyone has heard of, and if you win it, that can never be taken away from you." 

Bowen's eight-year-old mount is trained by Gordon Elliott while his brother James will be aboard Chantry House.
