The quarantine at Fair Grounds due to several cases of equine herpesvirus has had a ripple effect across the Thoroughbred industry, with Delta Downs rescheduling a pair of stakes that would have been decimated due to a lack of shippers, and Grade 1 winners Gun Runner and I'm a Chatterbox, both stabled at Fair Grounds, unable to travel for early-season engagements. The sales industry has not been left unaffected, with several prominent racing or broodmare prospects who most recently raced or trained at Fair Grounds forced to be scratched from this week's Keeneland January horses of all ages sale, as precautions against the spread of EHV-1 prohibit them from being on the sale grounds.
