The Queen's Carlton House is set to take his place in the Investec Derby at Epsom on Saturday after showing positive signs following an injury scare.
Connections of the colt, trained by Sir Michael Stoute, issued an upbeat bulletin this evening after the three-year-old showed no ill-effects following a four-furlong canter in Newmarket this morning.
Carlton House has been the long-time favourite for the premier Classic, but doubts over his participation arose after he developed swelling in his near-fore leg.
The Dante Stakes winner suffered the setback during a work-out on Monday.
"We are pleased to report that Carlton House did a good exercise this morning and he is very much still on target for Saturday's Investec Derby," Her Majesty's racing manager John Warren said.
Thirteen horses have been declared for the Flat highlight of the year, with Andre Fabre's Prix Greffulhe winner Pour Moi having also stood his ground.

Ballydoyle's two major hopes are Dante runner-up Seville and Derrinstown Stud Derby Trial winner Recital. O'Brien also saddles Memphis Tennessee and Treasure Beach.
