High Definition is on course for Saturday’s Dubai Duty Free Irish Derby, although Aidan O’Brien has yet to finalise his squad for the Curragh Classic.

The Galileo colt was the winter favourite for the Derby at Epsom after winning each of his two juvenile starts, before a blood disorder scuppered a planned Lingfield run and sent him to York’s Dante Stakes for a Classic prep.

High Definition finished third on his return on the Knavesmire and had been expected to line up at Epsom, only for O’Brien and Coolmore to rule him out three days before the Derby.

O’Brien said: “Everything has been good since he ran at York and the plan is for him to run at the moment.”

After relying on just Bolshoi Ballet at Epsom, O’Brien has a number of contenders at this stage for the Curragh, with a couple possibly making a swift return after running at Ascot.

The Mediterranean finished fourth in the King Edward VII Stakes, while Sir Lamorak was a fast-finishing second in the King George V Stakes. Both are in the frame, along with Van Gogh, who was well beaten by stablemate St Mark’s Basilica on his most recent run in the French Derby.

O’Brien added: “Some of the Ascot horses will be left in like The Mediterranean and Sir Lamorak. Van Gogh is another we’ve been thinking of and obviously as it gets closer we’ll narrow it down a bit more.”

The Ballydoyle handler also has Arturo Toscanini, Carlisle Bay, Matchless and Wordsworth among eight entries, with Bolshoi Ballet a notable withdrawal after his unplaced Epsom run.

The colt suffered a cut to his hind leg at an early point in the Derby and has not recovered in time to have another crack at Classic glory.

Meanwhile, Mojo Star defied odds of 50/1 at Epsom and will bid to go one better in Ireland after being added to the race. The Richard Hannon-trained colt remains a maiden after three runs, but was four-and-a-half lengths behind Adayar earlier this month.

Dante winner Hurricane Lane was third at Epsom for Charlie Appleby and could try again, while there is further British representation in the shape of the Martyn Meade-trained Lone Eagle.

Irish 2,000 Guineas hero Mac Swiney was fourth at Epsom and is in the mix for Jim Bolger, with Johnny Murtagh calling on Earlswood and Donnacha O’Brien running Fernando Vichi.
