The Juddmonte International at York on Tuesday will see the addition of the supplemented Dick Turpin to the starters, to be ridden by Richard Hughes.
Moving up to a ten furlong event at the Knavesmire, the Richard Hannon charge, who placed in the 2000 Guineas and St James's Palace Stakes and last time out won a merited Group One prize in the Prix Jean Prat, has Hannon hoping that he will have the stamina for the race.
Hannon had stated earlier in the week that supplementing the colt for the York competition had been decided against to instead have a shot at Saturday's Group 2 Prix Guillaume d'Ornano at Deauville.
Although, that decision now seems to have been reversed after Dick Turpin was listed with the potential twelve starters for the Group 1 competition at the six-day confirmation stage.
"John weighed up the options, and, with Dick Turpin having won him more than Â£470,000 in prize-money this season, he has opted to stump up the supplementary for York.
"John takes the view that Dick Turpin owes him nothing, and he is keen to have a go. Full marks to John for being sporting enough to have a crack, but, Richard Hughes said after the Prix Jean Prat at Chantilly that the colt would get a mile and a quarter, and he feels that York is the perfect track to try out his stamina."
He also said, "Dick Turpin is staying in training next year, so if he does stay it will increase our options as a four-year-old. He is in great form at home and we'll give it our best shot at York, but if he finishes in the first three, John will show a profit, and he'll get almost Â£35,500 if he is fourth."
Sky Bet's Matt Doyle said, "The presence of Dick Turpin in the field will add an extra dimension to the race now Harbinger is out and Richard Hannon will be challenging for the trainers' title if his star miler can win the coveted Group 1 stepping up in trip."
