(EW.com) -- Filming that does not involve horses will continue on HBO's critical fave "Luck" while the American Humane Association investigates the death of a third animal on the show's Southern California set.
The first-year drama from David Milch and Michael Mann has already earned a second-season pickup, so production was underway on the second of 10 new episodes when a horse was injured and euthanized Tuesday at Santa Anita Park in Arcadia. The animal reared and fell back while on its way to a racetrack stable -- a common occurrence in stable areas every year, according to a state racing board doctor. Still, a routine necropsy will be conducted and the AHA will investigate.
An AHA safety representative was at the track when the accident occurred, and according to an HBO spokesperson, "as always, all safety precautions were in place." The rep said that the network is "deeply saddened" by the animal's death.
