“There was a two horse collision on the training site,” said Martin, who explained to KNX 1070 Newsradio that one horse sustained catastrophic injuries.

“Both the riders and the other horse were uninjured,” said Martin.

The death follows the deaths of Uncontainable and Harliss – two other horses over the weekend, who died on-track. Both were euthanized after breaking their right front ankles.

Sunday’s death brings the total number to 42 since December 2018.

Animal rights activists protested at the track Sunday, calling for an end to the sport.

“We want to bring awareness to the public because we believe when the public knows better that they will do better and that they will fight to protect the rights and at this point the lives of animals that have no say or choice in this bloodsport,” said Amanda Lunberg of the group Horse Racing Wrongs.
