Mikhail Glinka, the Queen's Vase winner, who was recently sold out of Aidan O'Brien's Ballydoyle yard, will not be heading to Doncaster for the Ladbrokes St Leger on September 11 and was the most notable absentee from the 42 entries, with Coordinated Cut, PaddyPower and Berling, also missing.
Theology, trained by Jeremy Noseda, runner up behind Mikhail Glinka at Royal Ascot is on track for the event.
Harry Herbert, the owners Highclere Thoroughbred Racing's manager director, said, "Theology has come out of the Queen's Vase very well. It was a tough race and agony for horse, jockey and everyone concerned that he just lost out by a nostril.
"He is in good form now and Jeremy has been training him for Glorious Goodwood next week, either to run in the Gordon Stakes or the Goodwood Cup.
"We want to have a good look at those Goodwood races before we decide which one he runs in. We are hopeful that he will then continue to improve and the Ladbrokes St Leger will certainly be a target."
David Williams of Ladbrokes said, "The decision to put the closing date of the race back three weeks has certainly paid dividends by handing connections more time to consider if they have a Ladbrokes St Leger contender on their hands.
"We are naturally delighted to see such strength in depth among the entries for the 2010 Ladbrokes St Leger with several Classic winners among the possible starters on September 11."
