The Radlett handler will keep options open for the six-year-old gelding, who holds entries in both the Queen Elizabeth II Stakes and the Qipco British Champions Sprint Stakes.
After suffering a luckless outing in the Lennox Stakes, the Mount Nelson gelding met trouble in running once again when finishing second in the Hungerford Stakes at Newbury last Saturday.
Ivory said: "I'm going to give him a little bit of time to freshen him up.
"We'll see how he is and count back from Ascot as there is not much for him.
"He could not reel the winner back in on Saturday. He had to be switched at a crucial time and you can't afford to switch them at that speed in those quality races.
"He will win a big race and he will surprise everyone when he does, but he does deserve one."
Stewards' Cup hero Lancelot Du Lac could be stepped back up in class for the Group Three Prix de Meautry at Deauville on Sunday, with the Listed Hopeful Stakes at Newmarket 24 hours earlier another option.
Ivory said: "What the ground is like will make up our minds where we go.
"Lancelot Du Lac is very well and I'm really pleased with him. He won quite cosily at Goodwood, but he had luck on the day.
"It did take a bit out of him, but not an awful lot. We will have a look at the Ayr Gold Cup afterwards."
Ivory could also step Eirene up in class and trip for the Group Three Dick Poole Fillies' Stakes at Salisbury on September 7 after she landed a five-furlong Listed race at Newbury.
He said: "I could not find a Listed fillies' race over six (furlongs) for her, that's why we went back to five - there was no science behind it.
"We might run her in the Dick Poole now but she is also entered in one of those big sales races at Doncaster.
"There are also a couple of nice races in France later on for her."
