The two Group One-winning stars, trained by John Oxx and Marcus Tregoning respectively, feature among 23 confirmations for Saturday's race, which is the highlight of Newmarket's Champions' Day meeting.
However, they look set to face stiff competition from Russian Rhythm after Michael Stoute left in his 1000 Guineas, Coronation Stakes and Nassau Stakes winner.
Her owners Cheveley Park Stud are also represented by Carnival Dancer, who has finished fourth and fifth in the last two runnings of the race when trained by Stoute. He is now in the care of Amanda Perrett.
Stoute has taken out the Aga Khan's recently-disappointing colt Kalaman and the Breeders' Cup-bound Islington.
Other notable withdrawals include Tregoning's Mubtaker, Aidan O'Brien's High Chaparral, Hold That Tiger and Brian Boru, and the John Gosden-trained Ikhtyar.
O'Brien has left in Yesterday, who has not enjoyed the best of luck on more than one occasion this season, Statue Of Liberty and Middlemarch.
Godolphin look set to be represented by Grand Prix de Paris victor Vespone, while last year's winning trainer Barry Hills relies on Far Lane and Chancellor.
Brian Meehan's Arlington Million runner-up Kaieteur also stands his ground.
Meanwhile, Falbrav will be entered for both the Breeders' Cup Turf and the Breeders' Cup Classic at today's supplementary stage, ahead Saturday week's meeting at Santa Anita.
The Breeders' Cup has long been on trainer Luca Cumani's mind, but a tilt at the 10-furlong Classic has only recently entered the equation.
Final declarations are not due until Thursday week.
Cumani did confirm though, that Falbrav's regular partner, Darryll Holland, will be on board in preference to an American-based rider.
Elsewhere, Mark Johnston looks set to have at least two strings to his bow in the Darley Dewhurst Stakes on Saturday.
The Middleham trainer has three in the Newmarket Group One contest after yesterday's confirmation stage Lucky Story, Pearl Of Love and Duke Of Venice, who has been supplemented at a cost of £15,000.
A total of 23 remain in the race.
Dangers abound, not least the Roger Charlton-trained Middle Park winner Three Valleys.
Balmont, his immediate victim in that race, has been left in by Jeremy Noseda.
Marcus Tregoning's Snow Ridge is also likely to be very popular after his impressive victory in the Royal Lodge.
Aidan O'Brien is, as usual, well represented numerically with eight possibles, although he has yet to saddle a juvenile Group winner in Britain this season.
His squad for Saturday consists of Antonius Pius, Colossus, Grand Reward, Haydn, Newton, Old Deuteronomy, The Mighty Tiger and Troubadour.
There is further quality representation from Ireland in the shape of Dermot Weld's Grey Swallow, a 10-length winner of his sole start at Galway, although he could be rerouted to the Racing Post Trophy.
All the leading fancies stood their ground at yesterday's confirmation stage for the Tote Cesarewitch at Newmarket on Saturday.
The second leg of the 'autumn double' is traditionally one of the big betting handicaps of the season and ante-post punters will be relieved to see the likes of Distant Prospect, Shabernak, No Refuge, Inglis Drever, Direct Bearing and Numitas still in at this point.
Along with No Refuge, Inglis Drever and Numitas, Sir Mark Prescott had been due to saddle One Off in his attempt to land a £100,000 bonus following the victory of his Chivalry in the Tote-sponsored Cambridgeshire.
But the gelding, six times a winner this season, has been taken out.
