Horse racing officials will hold an emergency summit on Tuesday to review the "unusually high number" of deaths at Churchill Downs after two more horses were euthanized over the weekend, bringing the total number of deaths at the famous racetrack to 12. 

The Horseracing Integrity and Safety Authority (HISA) released a statement Monday announcing the emergency meeting and additional measures the organization would be taking after two more horses were euthanized on Friday and Saturday due to leg injuries sustained during races at Churchill Downs.

"HISA’s highest priority is the safety and wellbeing of the horses and riders competing under its jurisdiction. We remain deeply concerned by the unusually high number of equine fatalities at Churchill Downs over the last several weeks," the statement read.

"We continue to seek answers, and we are working diligently with Churchill Downs and the Kentucky Horse Racing Commission (KHRC) to mitigate any additional risk." 

HISA noted that in addition to investigating each fatality, a second probe into the racing and training surfaces at the home of the Kentucky Derby would be conducted by seasoned track superintendent Dennis Moore.
