ARCADIA, Calif. – Violent Ridge, who was second in the California Cup Derby for statebreds on Feb. 19, sustained a cut on a foreleg in a recent workout and will not start in the Grade 1 Santa Anita Derby on April 7, trainer Hector Palma said on Thursday. The injury required sutures to close the wound and will cost Violent Ridge three weeks of training, Palma said. Violent Ridge, owned by BG Stables, won an allowance race for California-breds at a mile on March 11. The $1 million Santa Anita Derby at 1 1/8 miles is expected to have a short field. The Grade 1 winners Bolt d’Oro and McKinzie lead a field that will probably include the Louisiana stakes winner Instilled Regard.
