Jockey Michael Hills has paid tribute to the Newmarket team responsible for treating the ill-fated Gray Pearl.

Newmarket’s on-course vets said Gray Pearl was put down after suffering an “apparent spinal chord injury” in an awful incident before the Qipco 1000 Guineas.

Aidan O’Brien’s ante-post favourites Camelot and Maybe head the entries for the Qipco 2000 and 1000 Guineas respectively.

Marco Botti would not be afraid to take on Frankel again after his stable star Excelebration trounced his rivals in the CGA Hungerford Stakes at Newbury.
