Mick Kinane has flu and will not be flying over to England to ride at Bath today.
Kinane had two rides booked this afternoon, including Deadly Nightshade for David Elsworth in the Listed European Breeders' Fund Lansdown Fillies' Stakes.
His agent in Britain John Hanmer said: "He has flu and won't be riding today and he told me to leave him off at Ascot tomorrow as well.
"He's not coming over until Saturday - he'll definitely be OK by the weekend."
