Aidan O'Brien is triple handed in the French 2000 Guineas at Longchamp on Sunday as he aims to lift the prize for the fourth time.
The Ballydoyle trainer will be represented by Highland Reel, War Envoy and Dick Whittington as he seeks victory in the race for the first time since 2007.
Karar has been supplemented into a provisional field of 19. The Francis-Henri Graffard-trained colt was added to the Classic by owners Al Shaqab Racing at a cost of 39,600 euros.
After scoring at the first time of asking, the son of Invincible Spirit found only subsequent Newmarket Guineas runner-up Territories too good for him in a Group Three at Longchamp last time out.
Karar is one of two entries for Graffard in company with the Pearl Bloodstock-owned Cornwallville.
Heading the list of four British raiders is the Charlie Hills-trained Greenham Stakes winner Muhaarar, while Saeed bin Suroor, who last won the race 10 years ago with Shamardal, relies on UAE 2000 Guineas hero Maftool.
Completing the British contingent is the Richard Hannon-trained Smaih, and Flaming Spear, who will attempt to give trainer Kevin Ryan a second French Classic having won the Prix du Jockey Club 12 months ago with The Grey Gatsby.
Andre Fabre's chances of claiming a sixth win rest with New Bay and Make Believe, while Pia Brandt will also have two chances following the declaration of both Hawke and Borsakov.
The field is completed by Sir Andrew, Mind That Boy, Tale Of Life, Mr Owen, The Commissioner and El Suzio.
