Qahriman, the first reserve for the Betfred Ebor, will run in the valuable handicap at York tomorrow after Harlestone Times was declared a non-runner.
The Luca Cumani-trained four-year-old was a two-length winner over course and distance in June and now sneaks into the 20-runner field.
Trainer John Dunlop has taken out Harlestone Times after he was found to be lame.
Jockey Kieren Fallon had been booked to ride the Richard Fahey-trained Area Fifty One, but he has switched allegiances to partner Qahriman, who will break from stall one.
Cumani has won the Ebor three times, most recently with Purple Moon in 2007.
