Connections of Nathaniel are considering supplementing the high-class colt into the King George VI and Queen Elizabeth Stakes.
The John Gosden-trained three-year-old was installed as favourite for the Ladbrokes St Leger after his five-length success in the King Edward VII Stakes at Royal Ascot.
He could, however, now compete against the likes of St Nicholas Abbey and Workforce in the midsummer Ascot highlight on Saturday week, as long as conditions were in his favour.
James Wigan, racing manager for owner Lady Rothschild, said: ‘It's up in the air at the moment, but we are discussing the possibility.
‘The ground will definitely be a factor, but good or good to soft would be fine.
‘It would be a big ask, obviously. The difficulty is that there are very few races at this time of year.
‘If you didn't go, where would you go?
‘It would depend on a few things, but if we were happy, and John felt the same way, then that would be our route,’ Wigan told the Independent.
