Former champion Carolina Marin retired in floods of tears from her Paris Olympics badminton semi-final on Sunday after her right knee buckled in distressing scenes.

But she could barely move, losing the next two points before falling to the ground again, clearly in great pain, and sobbing uncontrollably.

With the match over, she refused the use of a wheelchair and limped out of the arena to thunderous applause from the Paris crowd, a few of whom were moved to tears by her plight. The fourth seed had won the first game 21-14 and was leading 10-6 in the second.
