The 13-year-old gave local trainer Martin Keighley his first success at the biggest jumps meeting of the year when finally winning the unique cross-country test after finishing runner-up the two previous years.
The horse then went on to win a Cheltenham handicap chase in April for a third course win.
However, Any Currency now looks like being stripped of his Festival victory after triamcinolone acetonide (TCA) and its hydroxylated metabolite were found in a urine sample taken after the race.
The British Horseracing Authority will stage a hearing, at a date yet to be arranged, at which the disciplinary panel will have to decide whether Keighley is in breach of the rules of racing and if Any Currency should be disqualified.
TCA can be legitimately used for horses in training for various therapeutic purposes, but it is a prohibited substance on racedays which means it must not be present in a horse’s system.
Should Any Currency lose the race, runner-up Josies Orders, trained by Enda Bolger and ridden by Nina Carberry, will be promoted into first place.
Keighley declined to comment when contacted.
* Jim Bolger is hoping to see Moonlight Magic bounce back to his best in the Dubai Duty Free Irish Derby at the Curragh on June 17.
The Godolphin-owned colt was a leading contender for Epsom honours in the Investec Derby following his victory in the Derrinstown Stud Derby Trial at Leopardstown.
He had Epsom third Idaho behind him when winning at Leopardstown, but never looked happy when running downhill to Tattenham Corner and eventually came home last of the 16 runners.
Bolger said: “Moonlight Magic has been a bit quiet since, but there is nothing obviously wrong.
“We have done tests and are waiting to see if anything shows up.
“It was a similar story with Turret Rocks (seventh to Minding in the Oaks), and it just wasn’t our weekend.
“We’ll have to move on and hopefully we can aim at the Irish Derby and the Oaks (with Turret Rocks).
“They are two very nice prospects and I’ll be very surprised if we don’t get them back.”
* Tattersalls Irish 2,000 Guineas hero Awtaad is on course to further advertise his championship credentials in the St James’s Palace Stakes at Royal Ascot next week.
The once-beaten Cape Cross colt brought the house down at the Curragh last month as he gave octogenarian trainer Kevin Prendergast a second Irish Guineas, some 40 years after his first with Northern Treasure.
In doing so, Chris Hayes’ mount had Newmarket Guineas winner Galileo Gold in second, and while conditions may be slightly different for the eagerly-awaited rematch, Prendergast is not losing sleep over the likely Berkshire terrain.
He said: “Awtaad runs in the St James’s Palace.
“He doesn’t need cut in the ground and I’m happy with him.”
As well as the English and Irish Guineas winners, a third Classic scorer is likely to line up, with Aidan O’Brien aiming impressive French Guineas victor The Gurkha at the one-mile showpiece next Tuesday.
