A maximum field of nine runners, headed by Alamshar, will go to post in Saturday's Ireland the Food Island Champion Stakes at Leopardstown.
The brilliant John Oxx-trained three-year-old, who has won the Budweiser Irish Derby and the King George VI and Queen Elizabeth Diamond Stakes this season, is likely to be a warm order for the mile and a quarter event.
His regular partner Johnny Murtagh could yet be back to partner him as he returns from a self-imposed break with two rides for Oxx at Limerick tomorrow.
"Alamshar worked this morning and is in good order," Oxx said on Tuesday. "Johnny rode him on the Peat gallop and we're happy with him.
"As for the Champion Stakes and Johnny riding, we are still taking it one day at a time - we'll see how he goes on at Limerick on Wednesday."
The opposition is led by Aidan O'Brien's dual Derby winner High Chaparral, who made a successful return to action after injury with a smooth success over 10 furlongs at the Curragh last month.
The Ballydoyle handler has also left in the three-year-olds France and Statue Of Liberty.
Darley Irish Oaks winner Vintage Tipple has been left in by Paddy Mullins, while a surprise acceptor is Dermot Weld's Sagitta 2000 Guineas hero Refuse To Bend.
The British contingent is led by Falbrav, who is reported to be in top form by trainer Luca Cumani. The five-year-old has already won both the Coral Eclipse and Juddmonte International Stakes this season to make him the inaugural British Horseracing Board Middle Distance Champion.
Racecourse manager Tom Burke confirmed that there is little in the way of rain expected at the track this week.
"Our ground is good to firm at the moment and the forecast is for dry conditions Tuesday, Wednesday and Thursday," he said.
"There is some rain getting into the west of Ireland on Friday, but the present indications are that it may not even reach the east coast, but if it does it will produce very little in the way of rain."
