Joseph was the trainer for Parents Pride and Chasing Artie. Both horses collapsed and died on the track on Saturday and Tuesday, respectively, after the races.

KENTUCKY DERBY 2023: WHAT TO KNOW ABOUT THE FIRST STAGE OF THE TRIPLE CROWN OF HORSE RACING

Two other horses have died on the track in recent days. Take Charge Briana and Wild on Ice were euthanized after injuries, the latter of whom was set to run in the opening stage of the Triple Crown, but the cause of death for Saffie’s horses has not been revealed.

No horse trained by Joseph had died before Saturday.

Joseph said Thursday that investigators examined his stable, checked the horses’ veterinary records and took blood samples from each of his horses, which showed nothing abnormal. The feed, hay, straw and supplements used by the horses were also controlled.
