Galileo's Nathaniel is Another Arc Defection

   Lady Rothschild and Newsells Park Stud's Nathaniel (Ire) (Galileo {Ire}) will miss Sunday's G1 Qatar Prix de l'Arc de Triomphe at Longchamp. The John Gosden-trained 4-year-old, who won last term's G1 King George VI & Queen Elizabeth S. and this term's G1 Eclipse S., underwent blood tests–which were deemed unsatisfactory–when found to be running a temperature.
