Saratoga Special winner Ewing, unbeaten in his nascent career, will scratch from tomorrow's Grade 1 Breeders' Futurity at Keeneland and point to his 3-year-old campaign.
Trainer Mark Casse said that Ewing trained on Friday morning, but Casse "wasn't completely happy with him afterwards."
"He wasn't 100 percent, and he's always 100 percent," Casse added.
