You punch a horse ... you're outta the Olympics.
That's what happened to a modern pentathlon coach when she put hands on Saint Boy during the jumping competition.
Annika Schleu was having big problems controlling Saint Boy ... struggling to control the animal, who appeared spooked. Her German coach, Kim Raisner, was trying to help Annika, but the horse wasn't cooperating.
The way the competition works ... the riders only have 20 minutes with the horse before the competition ... she apparently had never ridden Saint Boy before, and the horse wasn't having it.
