Authorized heads 19 confirmations for the Vodafone Derby at Epsom on Saturday.
The colt is a hot favourite to give jockey Frankie Dettori his first victory in the world-famous Classic after gaining an impressive success in the Dante Stakes.
Peter Chapple-Hyam’s charge romped home by four lengths on his seasonal debut in the Group Two contest at York and he will bid to give the trainer his second Derby win after Dr Devious in 1992.
Aidan O’Brien, successful with Galileo (2001) and High Chaparral (2002), still has eight in the race – Acapulco, Admiralofthefleet, Anton Chekhov, Archipenko, Eagle Mountain, Mahler, Soldier Of Fortune and Yellowstone.
His one withdrawal is Chinese Whisper while Saeed bin Suroor may rely on Eastern Anthem after Godolphin withdrew Jalil and Mythical Kid.
There were no supplementary entries after John Gosden decided against adding Dante runner-up Raincoat to the field.
He is likely to take his chance in the French version instead but Gosden could still be represented by Lucarno.
Marcus Tregoning, successful 12 months ago with Sir Percy, relies on Aqaleem, while Sir Michael Stoute’s sole representative is Arabian Gulf.
Other notable entries include Regime, Salford Mill and Strategic Prince.
