NBC NATIONAL NEWS — A jockey was killed Thursday at California's Alameda Fair Race Track.
Jockey Jorge Herrera was killed when he was thrown from his mount in the eighth race at the Alameda County Fair in Pleasanton.
Officials say the 33-year-old jockey suffered a massive head injury when he either struck the ground or was clipped by another horse.
He died two hours later after being taken to a local hospital.
Bloodhorse.com reports that Morito, the horse Herrera was riding in the $5,000 maiden claiming race at five furlongs, came out slightly while racing between horses leaving the half-mile pole.
The 4-year-old gelding clipped heels with another horse, Tribal Sun, and stumbled badly, throwing Herrera.
Herrera is from Jalisco, Mexico.
He's won 55 races during his career.
