Brendan Powell has booked Kieren Fallon to ride Dark Emerald at Meydan on Thursday.
Dark Emerald, who has already won twice at this year's Dubai World Cup Carnival, will be bidding for victory in the Zabeel Mile (Group 2) contest.
Richard Mullen successful in the Nova Stakes and District One Handicap isn't available to take the ride on Dark Emerald as he is riding in Qatar.
Powell, speaking to www.cdhorseracingtours.com, said: "Dark Emerald has been an absolute star for the last couple of months. He's come out of his race so well and he keeps doing it we felt we had to give it a go.
"We've booked Kieren and we are delighted to have him riding he knows the horse well and has won and been placed on him. Richard Mullen is out in Qatar riding for his boss in the big race.
"Looking at the Zabeel Mile race, it's serious prize money - even to be placed would be fantastic. There are only two horses rated higher than Dark Emerald (112) and this is really his proper trip, we've got a nice draw and we just need some luck in running and hope we don't get boxed in," he concluded.
Dark Emerald's two wins and a second-place finish at Meydan racecourse this winter have seen his rating rise to 112.
