Gary Tanaka’s Sudan, projected as the probable pace setter in the Arlington Million (gr. IT), was withdrawn from the race Aug. 8.

“He was fine when he galloped yesterday,” trainer Bobby Frankel said. “But when we scanned him this morning we discovered that the horse had bowed a tendon.”

Sudan, an Irish-bred son of Peintre Celebre, finished fourth in Belmont’s Man o’ War Stakes (gr. IT) in his last start July 12, and captured the grade III Golden Gate Fields Turf May 31. The 5-year-old chestnut was in a position to give prominent owner Tanaka his first win in the Arlington Million Aug. 9. Frankel has won the Million twice, one less than fellow Hall of Famers Charlie Whittingham and Ron McAnally, who hold the record for total victories.

In other news, Derrick Smith, Michael Tabor and Mrs. John Magnier’s Mount Nelson, the first winner of Great Britain’s group I Coral-Eclipse Stakes to challenge in the Arlington Million, got his first exercise over the local grounds Aug. 8
