Nico de Boinville paid Constitution Hill a visit on Tuesday and said the former champion hurdler is feeling “a bit sorry for himself”.

Nicky Henderson’s stable star has had no end of health trouble this season, scoping dirty in January and then being laid low with an infection which ruled him out of the defence of his Champion Hurdle title.

Just when connections had hoped for some light at the end of the tunnel and a possible run at Punchestown, he was then struck down by suspected colic and spent a few nights at the vets.

It was a relieved Henderson that informed everyone on Monday he was now back at Seven Barrows and De Boinville was keen to check in on him.

“Everyone has been kept in the loop. I went to see him this morning and hopefully he picks up in the next couple of weeks,” he told Racing TV.

“He’s certainly feeling a bit sorry for himself and I can see why.”

Tributes have been paid to Cheltenham Gold Cup-winning trainer Mark Bradstock, who has died aged 66.

Along with his wife Sara, Bradstock trained Coneygree to become the first novice since Captain Christy 41 years earlier to land the blue riband at Prestbury Park in 2015.

The Old Manor Stables handler also saddled Carruthers to win the 2011 Hennessy Gold Cup at Newbury, while Step Back was another big-race victor in the 2018 bet365 Gold Cup at Sandown.

Coneygree was ridden at Cheltenham by Nico de Boinville, who is now established as one of the top riders in the sport.

He wrote on X (formerly Twitter): “Thinking of the Bradstock family. I owe them all so much, they played an integral part in getting me going. Mark will be hugely missed.”

Bradstock’s final runner Mr Vango won the Devon National at Exeter on February 23 by 60 lengths and could now line up in the National Hunt Chase at the Cheltenham Festival later this month.

Retired jockey Mattie Batchelor, who was on board Carruthers for his Hennessy triumph and also steered Coneygree to two Grade Two victories over hurdles, posted: “Thank you very much for the memories!!!! We had some great times and more importantly some great laughs!!!!! Condolences to Sara, Alfie (son) and Lily (daughter).”

Nico de Boinville knows Constitution Hill’s electrifying jumping leaves “no margin for error” – particularly in the white-hot cauldron of the Unibet Champion Hurdle.

Nicky Henderson’s star is chasing a second successive win in the race having demolished State Man by nine lengths last year.

There are those who feel State Man has enjoyed a better preparation this term, and he has won four Grade Ones since that reverse while Constitution Hill has only been seen once since April.

However, De Boinville has full faith that Henderson is the right man for getting a horse to peak on the big day.

“I couldn’t have been happier with him at Kempton. State Man has gone and done what he does on that side of the Irish Sea, but there are still four weeks to go and you are just keeping all fingers crossed,” De Boinville told talkSPORT2.

“I’ve been going there before with the likes of Altior and at the last minute things go wrong, so you are just hoping everything goes right and we have a very good prep.”

Regarding his mount’s incredible jumping technique he went on: “You really do feel like there’s no margin for error because you are going so fast, you are literally just clipping the top bar. You are going very, very quick and there will be no exception in the Champion Hurdle, it’s going to be run at a very good pace and hopefully the right horse wins.

“He’s (Henderson) definitely not one to doubt. If the weather hadn’t stopped us, he would have had two runs and no one would be saying anything as he’d have gone to the Fighting Fifth and Christmas Hurdle, so ultimately we were stopped because of the weather.

“Hopefully he’ll be busy enough in the spring, you can go to Aintree and Punchestown after Cheltenham if he comes through it well.”

Henderson and De Boinville enjoyed a good day at Newbury on Saturday when Iberico Lord won the feature Betfair Hurdle, but perhaps more importantly Shishkin booked his Gold Cup ticket with a straightforward win after an interrupted season.

De Boinville said: “It was very encouraging. I heard someone refer to him as an inconsistent horse, but I tend to disagree with that. Once he sets off he tends to put up really good runs and more often than not he’s somewhere near the winner’s enclosure.

“I had no doubts on Saturday, from the point I got on him in the paddock he was raring to go and wanted to get on with it. As soon as I lined up he was happy, the tapes went up and away he went.

“I was happy with him, he took a good blow as well so it was a really good prep race for him going towards the Gold Cup.

“One thing that Shishkin does do is finish strong, over three miles or two. He’s quirky in a sense that he can race behind the bridle, race lazily and the suddenly pick it up again, you just have to keep encouraging him forward.

“I think he’s best of the British. I’m looking forward to seeing what L’Homme Presse does at Ascot, but Galopin Des Champs definitely sets the standard, I’d like to think we’d definitely serve it up to him.”

Iberico Lord came out on top for Nico de Boinville and Nicky Henderson in the Betfair Hurdle.

In a field of 21, the bay was an 11-2 chance to give Henderson a sixth victory in the race and land himself another big handicap after taking the Greatwood in November.

Under a neat ride from De Boinville, the six-year-old was always handy and was one of a handful in contention over the final flight.

He landed marginally behind 28-1 shot L’Eau Du Sud but battled all the way to the line to score by an eventual two and a quarter lengths.

Nico de Boinville will miss Friday’s action at Sandown and the plum ride on Jonbon at Cheltenham on Saturday to give himself more time to fully recover from the broken collarbone he suffered in a fall at Doncaster last month.

The leading jockey returned from nearly a month on the sidelines at Lingfield last Sunday and has since taken up a total of 11 rides, including a winner at Warwick on Monday.

However, having suffered a narrow defeat aboard 11-8 favourite Ilfu Un Mome at Chepstow on Wednesday – his only ride on the card – De Boinville has made the difficult decision to withdraw from the upcoming action, meaning James Bowen will take over aboard Jonbon in Saturday’s Clarence House Chase.

“Nico was sore after yesterday, so he won’t be riding this weekend,” said De Boinville’s agent Sam Stronge.

“We’ll just take it day by day and see how it is next week. It’s unfortunate, we obviously tried to do our best as quickly as we could, and after riding for a couple of days he obviously wasn’t quite right.

“The sensible thing to do when you’ve got big rides like that (Jonbon) is to not let everybody down. It’s a very difficult decision, but we’ll take it day by day and hopefully he’ll be back next week.”

Nico de Boinville is poised to make his return from a broken collar bone at Market Rasen on Friday.

The rider was injured in a fall at Doncaster on December 29 but should he pass the doctor on Thursday, De Boinville will make his comeback on two mounts for his boss, Nicky Henderson, at the Lincolnshire track.

However, not only does De Boinville need to get medical permission to resume riding, he also needs the meeting to pass a precautionary inspection at noon on Thursday due to the current cold spell.

De Boinville does appear to have won his race against time to take the plum mount on Jonbon in Saturday’s BetMGM Clarence House Chase at Ascot – although that meeting is also subject to the weather. He would clearly be in pole position to ride should the meeting be moved to Cheltenham the following week, as happened last year.

The situation neatly sums up the life of a National Hunt jockey as De Boinville has only taken the reins on Jonbon this season as regular partner Aidan Coleman remains sidelined himself.

Henderson said: “He’s got to pass his medical tomorrow and if he passes that then he’s fine to ride.

“Obviously James (Bowen) has stepped up brilliantly in his absence but Nico has been riding out since last weekend.

“Nico knows them all inside out but James is in here everyday as well, he knows them all too.”

De Boinville is scheduled to ride Jemura in the Read Nicky Henderson’s Exclusive Unibet Blog Handicap Hurdle and Kutaiba in the Listed  Unibet 3 Uniboosts A Day Alan Swinbank Mares’ Standard Open NH Flat Race.

Looking ahead to Ascot, Henderson said: “It’s such a pain with the weather as everyone is really looking forward to it. We hope it will be all right.

“I don’t see why we wouldn’t go to Cheltenham next week if that is what happens. I’ve seen they’ve said El Fabiolo probably won’t travel twice, but it is pointless me speculating what they might or might not do.

“All I know is we are very happy with Jonbon, we couldn’t be happier and we were really looking forward to the race, I’m sure a lot of people were, and hopefully it will still take place with both of them running.

“We haven’t been held up by the weather, the only thing we can’t do is school on grass but we’ve got an all-weather schooling strip as well and an indoor school, so otherwise everything is fine.

“I’m trying to be an optimist, but I’m finding it quite hard.”

Nico de Boinville will miss key rides aboard highly-touted duo Willmount and Jeriko Du Reponet at Newbury on Saturday following a fall at Doncaster on Friday.

The 34-year-old was riding 13-8 favourite Therapist for his boss Nicky Henderson in the La-Z-Boy At KC Sofa’s Fillies’ Juvenile Maiden Hurdle when coming to grief at the second-last flight, suffering a suspected collarbone injury.

It continues a mixed Christmas period for the rider who tasted success aboard his star mount Constitution Hill and hot Triumph Hurdle prospect Sir Gino at Kempton, but was unseated from Shishkin at the second last when leading Boxing Day’s King George VI Chase.

De Boinville told Sky Sports Racing: “I think it’s a collarbone job. I’ve got to go to the X-Rays and see how we are.

“What can you do, you can’t cry about it.”

Fresh from a first Grade One victory at Aintree on Boxing Day, it is fellow Seven Barrows rider James Bowen who will take De Boinville’s place aboard Willmount in the Coral Challow Hurdle and Supreme Novices’ Hurdle favourite Jeriko Du Reponet in the Coral Committed To Safer Gambling ‘Introductory’ Hurdle.

Bowen also picks up the ride on Steal A March for the King and Queen on the Newbury card, with David Bass taking Bowen’s place aboard outsider Brave Jen in the Challow.

Willmount made the perfect start to life over obstacles with an effortless win in the Agetur UK Novices’ Hurdle at Newbury.

Trained by Neil Mulholland last season to win two bumpers, he moved to Nicky Henderson over the summer and the change of scenery has certainly not done him any harm.

Nico de Boinville found himself in front aboard Oli Harris’ £340,000 purchase after half a mile due to the speed at which his mount was jumping and from then on it was a solo affair.

Only Beny Nahar Road and Onewayortother attempted to keep pace but when De Boinville kicked clear on the turn for home and pinged the third last, the race was over and he cruised to a 13-length success.

“He gave me a lovely feel actually. There wasn’t much pace on so I was happy to just roll away down the back, he pricked his ears nicely and quickened away into the straight,” De Boinville told Racing TV.

“He jumped very nicely, was slick when he needed to be and he could fiddle away as well, which is great.

“He’s very uncomplicated, these pedigrees are showing more and more with their temperament and everything.”
