Del Mar racetrack officials have suspended turf races after another horse was seriously injured Thursday, bringing the total of race-related, equine injuries to eight since the season's start.
During the seventh race of the day, a filly named "Serious" was badly hurt while sprinting on the turf.
It's unclear what kind of injuries the horse sustained, but the animal will be taken from Del Mar to Los Alamitos, the home base of its trainer and owner.
In response to the incident, Del Mar officials have canceled turf racing for the next three days as crews perform more maintenance on the track.
They hope to return to regular racing on Wednesday.
The Del Mar Thoroughbred Club began making changes to its new turf Sunday after seven horses were euthanized due to race-related injuries in just the first ten days of the season.
Four of those deaths have been after falls on the new turf.

Another horse died after a morning workout on Opening Day, July 17.
Officials say a number of elements factor into a race horse's injury -- not just the type of track -- but adjustments like extra watering and aerating the grass are being made.
Officials also moved the inner rail 18 feet so horses wouldn't be running on as many divots and holes in the turf.
