As TMZ reported, yesterday a third horse died during production of the show, and HBO just made the drastic decision to lower the boom.

The statement goes on ... "We maintained the highest safety standards throughout production, higher in fact than any protocols existing in horse racing anywhere with many fewer incidents than occur in racing or than befall horses normally in barns at night or pastures."
