Carolina Marin in tears after knee injury forces her to withdraw in Olympics

Devastated former Olympic champion Carolina Marin withdrew in tears from her badminton semi-final on Sunday after her right knee buckled in distressing scenes. Marin, who won women's singles gold at the Rio 2016 Games, was on track to reach the final but collapsed midway through the second game against China's He Bingjiao.

Coaches and He rushed to her side as she lay on the ground for several minutes, clutching her leg. She eventually got up and walked off the court then resumed wearing a support but she could barely move, losing the next two points before falling to the ground again and retiring.

Marin, the fourth seed in Paris, won the first game 21-14 and was leading 10-6 in the second before she left the court in tears before going for a medical check.
