2The gymnast who landed on her head during her floor routine
Downie had gotten through uneven bars and balance beam without incident, but at the halfway point of her floor routine, she tried to perform a flip with two-and-a-half twists directly into a tucked front flip. She didn't have enough control to get her body completely around, and landed directly on her head and neck. Downie picked herself up and tried to finish, but stepped off the competition mat instead.
Her coach and medical staff assisted her out of the arena and to the hospital. Thankfully, her injuries were not serious. She soon returned to compete on vault and qualified to the all-around final. (Source)

5The equestrian who gave up her Olympic dreams for her sick horse
While visiting Parzival, Cornelissen noticed the right side of his head was swollen, and he had been kicking the walls in his stall. She checked and — sure enough — Parzival was running a fever.
It is believed he was bitten by an insect which produces toxins. He was given fluids, and X-rays were taken of his jaw. When his temperature dropped and the swelling had subsided, vets and the team coach gave the horse the green light to compete.
Cornelissen took him to the arena but wasn't convinced — instead she put her dreams of competing aside for his well-being. "When I entered, I already felt he was giving his utmost and being the fighter he is; he never gives up... But to protect him, I gave up," Cornelissen said. "My buddy, my friend, the horse that has given everything for me his whole life does not deserve this.... So I saluted and left the arena." (Source)

8The Italian cyclist whose Olympic dreams were dashed after a collarbone break
Many believe Rio's treacherous road race course, while scenic, is to blame. Chris Boardman, a cycling commentator for the BBC and former-Olympic track cyclist, said, "“I went down and had a look at the course and saw those edges. We knew it was way past being technical; it was dangerous. I looked at that road furniture and thought, ‘nobody can crash here and just get up.'" (Source | Photo)
9The groom who was kicked in the head by a competing horse
As the medals were awarded, Sanderson was parading Sönke Rothenberg's nine-year-old horse, Cosmo, when it reared up, caught him on the head, and knocked him to the ground. Blood gushed from his forehead, as a replacement groom held Cosmo for the remainder of the ceremony. Robbie left the arena with a towel pressed to the wound, and was taken to the hospital to have the injury assessed, but he appears to be okay. (Source | Photo)
