I enjoy watching eventing however I’m not very familiar with the rules.
COTH is reporting that a rider received a yellow card for “Abuse of Horse—Riding an exhausted Horse". The article says the rider finished the cc and was later eliminated by the ground jury.

I looked at the FEI rule cited and it explains “If not directly witnessed by the Ground Jury, the incident must be reported as soon as possible to the Ground Jury through the Secretary of the Organising Committee or Cross Country Control Centre as appropriate. Where possible the report should be supported by a statement from one or more witnesses.”
My question: if the GJ notices the exhausted horse while it’s on course, do they (can they) signal the rider to stop ? If yes, how is the rider signaled ? T.I.A.
