Epsom Handicap favourite Rock Sturdy has been ruled out of Saturday's race with a leg injury.
The Joe Pride-trained four-year-old will undergo scans to determine the extent of the injury to his near fore suspensory ligament.
The Epsom (1600m) at Randwick is one of three Group One races at the Randwick meeting which also features the Metropolitan Handicap (2400m) and the Flight Stakes for three-year-old fillies.
