Sword Fighter is set to be aimed at the Ladbrokes St Leger at Doncaster after his Royal Ascot win in the Queen's Vase last week.
The Aidan O'Brien-trained three-year-old was a surprise 33-1 winner over two miles but is in line to drop down in trip for a Classic trial, probably the Great Voltigeur at York.
O'Brien said: "He's a staying horse. We will give him a little break and then look at something like the Voltigeur at York before the St Leger.
"He's a tough horse and stays forever."
Sword Fighter was one of a record-equalling seven winners over the five days for O'Brien, matching a mark set by the late Sir Henry Cecil.
"You are never confident but you are always hopeful. We had a lot of nice horses to run but the ground went against us a bit and we didn't really know what was going to happen," said O'Brien.
"We had some with good chances but as a team they ran well, and really we couldn't have been happier. Order Of St George (Gold Cup) was very impressive and so was Caravaggio (Coventry Stakes).
Of Order Of St George he said: "I'm going to give him a break now, and we'll have a look at a trial before the Irish St Leger.
"It wouldn't be fair on him to keep going now, especially if the ground is firm.
"He will be entered for the Melbourne Cup. Lloyd (Williams, four-times Melbourne Cup-winning owner) loves the race and is a major stakeholder in the horse. There is also the Arc if the ground is on the slow side."
Looking back at the performances of some of his other stars last week O'Brien said: "We would like to take on Galileo Gold again with The Gurkha. He will stick to a mile and the Sussex Stakes is the race we are looking at.
"Found is on a break now and then we will have a look at starting her back for the autumn with a run before the Irish Champion Stakes with a view to going on for the Arc - a bit like last year.
"She probably really comes into her own in the second half of the year. She loves racing, and is a big, hardy, genuine mare.
"Churchill was very green when he got to the front. I was afraid and a bit worried that he would be too green. He's going to be a very smart colt."
