Russian athlete suffers horrifying mid-dive mishap

A Russian diver has managed to walk away uninjured after a diving platform collapsed during preparations for the Rio Olympics in Havana, Cuba.

Sergey Nazin was executing a synchronised dive with his partner when the diving board suddenly felt apart.

While his partner executed the planned dive, Nazin fell awkwardly and narrowly avoided hitting his head on the platform.

"Nothing too bad happened in here, Nazin regrouped, and the Cuban side has already fixed everything," Oleg Zaytsev, Russian national diving team coach, said.

"I remember many similar accidents, including ones when divers hit the boards with their heads.

"Once that happened to three times gold Olympic champion Gregory Louganis.

"The competition had to be stopped, so the doctors could check on him. But he returned to the action and won his fourth gold medal that day," said Zaytsev.

It hasn't exactly been a great couple of days for Olympic hopefuls:
