A person suffered "a serious injury" following an incident at the stable yard at Kempton's meeting on Saturday evening, a representative of the racecourse told Press Association Sport.
The all-weather fixture had to be abandoned with two races remaining.
Clerk of the course Barney Clifford told the Press Association: "There is a serious injury in the stable yard - the person is in a serious condition."
A statement issued by the Kempton stewards said that the doctors at the track had to "attend a medical emergency".
The statement read: "The stewards held an inquiry following a report from the clerk of the course that a serious incident had occurred in the stable yard prior to race seven.
"They interviewed the clerk of the course who was representing the racecourse executive.

"This decision was sanctioned by the stewards."
