DEL MAR, Calif. — Two horses were euthanized and another horse was injured Sunday during three different races at the Del Mar Racetrack.

The fatalities occurred on the third day of the track’s fall meet, which began on Nov. 8 and is scheduled to last through Dec. 1.

A 3-year-old gelding named Ghost Street was making his fourth career start Sunday during the track’s third race of the day when he suffered an injury to his left leg. The horse was euthanized, the racetrack said.

The second fatality of the day was reported not long after, when a 3-year-old colt named Prayer Warrior was injured during the track’s sixth race of the day.

A third horse was injured during Sunday’s second race. According to the Del Mar Racetrack, a 5-year-old mare named Princess Dorian suffered a leg injury and was taken to the San Luis Rey Equine hospital. Princess Dorian’s trainer, Andrew Lerner, said Sunday evening that she would undergo surgery for her leg on Monday.

Horse racing came under intense scrutiny this year, largely due to the dozens of racehorses that died while racing and training at Santa Anita Park. Santa Anita concluded its autumn racing season on Nov. 3 after 37 horses died at the track since Dec. 26 — including one in the Breeders’ Cup Classic, one of the sport’s most prominent events that offers a $6 million purse.
