Connections of narrow Gold Cup runner-up On His Own have decided not to appeal the decision of the Cheltenham stewards who left the placings unaltered following a lengthy inquiry after the race.
The Willie Mullins-trained On His Own was carried to his right by the winner Lord Windermere inside the final 100 yards and the stewards took a good 15 minutes to come up with their result.
They decided that the interference was not severe enough to alter the outcome and Jim Culloty was allowed to enter the history books as only the fifth man to have trained and ridden the winner of the big race.
In the immediate aftermath Mullins and owner Graham Wylie said they would discuss the possibility of an appeal but they have now decided to accept their fate.
"Of course we're not appealing, that wouldn't be a very sporting thing to do" - Graham Wylie
Mullins said: "We're not appealing. Having chatted with Mr Wylie we've decided not to."
On His Own was a late supplementary entry into the race and Wylie was thrilled by his display.
"Of course we're not appealing, that wouldn't be a very sporting thing to do," said Wylie.
"He ran a great race and I'm so proud of him, I'm happy with second.
"I know he was supplemented but I actually thought it was a two horse race between Bobs Worth and Silviniaco Conti, and over the last it looked that.
"Ruby (Walsh) said before it he might finish fourth but he could sneak third and he did even better than that.
"I don't think he'll run in the National, it comes very quick and he had a hard race so we're looking towards Punchestown, I think."
Lord Windermere's jockey Davy Russell also won the Triumph Hurdle on Tiger Roll and the Grand Annual on Savello on a golden afternoon.
Russell's fortunes turned full circle after earlier in the season being effectively sacked by Gigginstown House Stud as their leading rider and replaced by Bryan Cooper.
With Cooper injured, Russell stepped in on Gigginstown's Tiger Roll and Savello.
"After jumping two or three fences there was only one way I was going to be able to win the Gold Cup, I just had to try and creep into it. Sometimes it works out," Russell told Racing UK.
"Once I'd seen the video of the finish, my horse was idling in front and pricking his ears, I'm sure the stewards took the view that the best horse won and I hadn't caused enough interference to stop anybody else winning.
"It's a day I'll remember for a long time.
"There was very little I could have gained by showing my disappointment (at losing the job), that's just the way it was, they made their decision which they are entitled to do.
"I was lucky that when I wasn't going so well people still used me and that made a difference."
Plans remain fluid for Bobs Worth after he failed in his defence of the Gold Cup.
Nicky Henderson's nine-year-old had won at the last three Festivals, but he could only finish fifth behind Lord Windermere
Stablemate Triolo D'Alene travelled well for a long way in the race before he weakened into 10th place under Tony McCoy.
The Hennessy winner is, however, still on track to compete in the Crabbie's Grand National at Aintree on 5 April.
Henderson said: "All is absolutely fine with both horses.
"There are no dramas with Bobs and Triolo, but there were obviously plenty of dramas in the race.
"Triolo is still on course for the National, but we need to think about various things with Bobs."
Cheltenham specialist The Giant Bolster ran another honourable race to take third spot, beaten just three-quarters of a length.
David Bridgwater's nine-year-old has now been placed in the last three Gold Cups but is unlikely to run again this season.
Bridgwater said: "We were the top English horse, which I thought might be the case, and the only horse to represent Gloucestershire, so it was another brilliant day.
"There's not a bother on him and he's in great old nick.
"I would say that will be it for the season, but I obviously need to talk to his owner about that.
"I don't really see any point in running him again and we'll look again to the Gold Cup next year.
"For the horse to be placed in three Gold Cups is now pretty phenomenal."
