3-year-old horses, developmental equivalents of human children, should not be inexplicably collapsing on racetracks:

Tuesday morning at Del Mar, Eddie’s First fell on (and pinned) jockey Amir Cedeno (which is why we know about it). According to U-T San Diego, the Doug O’Neill-trained colt “escaped” with a bloody nose.

Yesterday at Saratoga, Lavender Road, trained by Abigail Adsit, was on her way to the gate for the 7th race when the jockey noticed she “wasn’t herself.” She was then scratched. This followed (Times Union):

“After Lavender Road was scratched, she was being led back to the paddock, but she never made it. Before getting there, she flipped over and was laying on the track right in front of the entrance into the paddock. At first, it was believed Lavender Road was suffering from some sort of heat exhaustion, even though temperatures at the Spa were in the 70s with low humidity.

The filly was being treated with water, ice and intravenous fluids. She was coaxed into getting on her feet, and she did. She got up 10 times, but each time she got on her feet, she would fall back to the ground. She never looked sound on her feet and was never standing for more than a few seconds. Finally, the filly was tranquilized and put on a mat and then dragged into a horse van.”

Trainer Adsit says her filly “suffered head trauma when she fell.” Asked for a prognosis, Adsit replied, “We’ll know better tomorrow. She’s stabilized. If her body absorbs the head trauma, she’ll be OK.” This is horseracing.
