The ante-post favourite for Sunday's Prix de l'Arc de Triomphe, Ace Impact, has been handed stall eight of the 15 runners. The sole Irish-trained runner, Continuous, will break from stall seven.
A low to middle draw is considered an advantage.
Hukum will have to overcome an unfavourable draw in stall 14.
The Owen Burrows-trained six-year-old won the King George VI And Queen Elizabeth Stakes at Ascot when last seen in July, having beaten Derby hero Desert Crown in the Brigadier Gerard Stakes at Sandown, when both horses were returning from long absences.
However, Hukum did not enjoy much luck in Thursday’s draw ceremony, with only Simca Mille on his outside in a 15-strong field.
Two winners have emerged from stall 14 since 2000, with Frankie Dettori producing a memorable ride aboard Golden Horn in 2015 and Dalakhani winning under Christophe Soumillon in 2003.
Hukum’s big-race pilot Jim Crowley will now be studying the tapes of the heroics of his weighing-room colleagues ahead of his ride aboard the Shadwell-owned contender in the French capital.
“I’m sure Jim will be doing all that, but there’s absolutely nothing we can do,” said Angus Gold, racing manager for the owners.
“Golden Horn had a lot of tactical speed, he went forward and stayed out wide and got a brilliant ride.
“There is no point making a fuss about it as there is nothing we can do.
“We’ll just have to work around it, see how he breaks and go forward and hope to slot in somewhere.”
The Ralph Beckett-trained Westover, beaten just a head by Hukum at Ascot, will be on the inside in stall one, with Free Wind – Dettori’s final Arc mount – in three for John and Thady Gosden.
Bay Bridge, representing Sir Michael Stoute, completes the British and Irish challenge in stall six under Richard Kingscote.
German Derby and Prix Niel victor Fantastic Moon was also supplemented and he will be in stall 12, with fellow German raiders Mr Hollywood and Sisfahan in 10 and 13 respectively.
Prix Niel second Feed The Flame and Japanese runner Through Seven Seas are also drawn low in two and five, with Haya Zark (four), Onesto (nine) and Place Du Carrousel (11) rounding out the field.
The ground at ParisLongchamp is expected to be good to soft, with a reported 25% chance of light rain on either Thursday or Friday and no watering planned.
