This is the horrendous moment a French gymnast's Olympics were ended in a single moment after he severely broke his left leg while landing on a vault.
Samir Ait Said's leg snapped as he tried to complete his vault during team preliminaries on Saturday, with the sound of the injury echoing through the arena.
As he crumpled to the floor, Said writhed in agony while medical officials tended to him in front of a shocked crowd.
After a delay of several minutes, he was eventually wheeled out and raised one arm to acknowledge the loud ovation he received from the crowd.
Several viewers watching on television took to social media to express their shock after the incident was broadcast live, with many detailing the loudness of the 'crack'.
The injury means Said will leave the Olympics prematurely, having also been expected to compete in the men's parallel bars, the individual all-round, the team all-round, floor exercise, rings and the pommel horse.
The injury came minutes after Germany's Andreas Toba hurt his knee during floor exercise.
Toba abandoned his routine and was helped off by trainers but managed to compete on pommel horse before exiting to receive medical attention.
