LOUISVILLE, Ky. - El Kabeir will not run in Saturday's Kentucky Derby because of an injury to his left front hoof. Trainer John Terranova II notified Kentucky Horse Racing Commission stewards of the scratch Friday afternoon, reducing the field to 19.

All betting numbers remain the same, but post 1 will be left empty to give the inside horses more room to maneuver. Ocho Ocho Ocho (No. 1) will start from post 2. Every horse will run from a post one numeral higher than its betting number.

Terranova, a native and resident of Syosset, said he canceled a morning gallop Friday because El Kabeir took "a few cautious steps. He has a tender spot in the inside corner of his left front foot."

Hours before he withdrew him, Terranova said he was taking the reversal in stride. "It's part of the game, part of being a trainer," he said. "We'll do what's best for the horse."

El Kabeir has four wins in nine starts for Terranova, whose only Derby runner, Falling Sky, finished 19th in 2013. The gray Florida-bred is owned by Ahmed Zayat, who also owns Derby favorite American Pharoah and long shot Mr. Z.

Notes & quotes: A bruised foot will prevent Palace Malice from facing Tonalist in Saturday's Westchester Handicap at Belmont Park, canceling a matchup of the past two Belmont Stakes winners. Co-owner Cot Campbell said Palace Malice would be aimed at the Met Mile on the June 6 Belmont undercard.
