The return of Juvenile Filly champion Caledonia Road has been delayed due to a virus she contracted shortly after her latest work two weeks ago.  Trainer Ralph Nicks said the Breeders' Cup Juvenile Filly winner continues to go to the track and train lightly but will not return to the work tab until she's completely back in her feed tub and there is no timetable set for her 3-year-old bow at this time.
