Jockey Javier Castellano will replace Kent Desormeaux on Zuzanna (8) in Friday's second race, an optional claimer at a mile on turf.
Zuzanna was Desormeaux's only mount on Friday's program following the withdrawal of Top Brass from the also-eligible list in the 10th race.
Steward Luis Jaurgeui said Desormeaux was "not feeling well" on Friday morning.
Desormeaux has one mount on Saturday's program - Apache Princess in the Grade 3 Sen. Ken Maddy Stakes for female turf sprinters. Desoremeaux does not have any Breeders' Cup mounts this weekend.
