Kasthari and Millenary, who fought out a thrilling finish to the Doncaster Cup last month, may go head-to-head again at Newmarket on Saturday.
The pair, who dead-heated on Town Moor, are among 19 declared at the five-day stage for the Persian Punch Jockey Club Cup, which is being run this year in the name of the ill-fated stayer who landed the spoils 12 months ago in a memorable finish.
On that occasion, Millenary and Kasthari finished second and third respectively.
Trainer Howard Johnson is using the race this year as a springboard to a winter campaign over hurdles for the latter.
David Elsworth has entered both Gold Medallist and Romany Prince in the Group Three contest, while Godolphin have the option of running Delsarte and Fight Your Corner.
Lonsdale Cup winner and Irish St Leger third First Charter is the sole entry from Sir Michael Stoute, while Marcus Tregoning could run Cumberland Lodge Stakes winner High Accolade.
Other notable entries for the two-mile race include Alcazar, Defining, John Oxx’s Irish raider Mkuzi and the Nicky Henderson-trained Dancing Bay.
