There’s been a highly unusual moment in the Olympic mixed doubles bronze medal match, with a Russian curler falling hard on her backside.

Russia’s Anastasia Bryzgalova was standing with her teammate Aleksandr Krushelnitckii and strategizing over where to send their last rock of the third end, or round, of Tuesday’s match. Suddenly, she seemed to lose her footing. She recovered, but seconds later, her foot went flying out from under her. She promptly landed on her backside.

The fall drew gasps from the stunned crowd. It is very rare for a curler to fall in professional curling.

Russia is playing Norway for the bronze medal in mixed doubles.
