Viral Olympics GIF allegedly shows Team China speed skater push puck to trip Team Canada opponent
... The moment in the women’s 500-meter quarterfinal was captured in a GIF that went viral on Reddit before being deleted and subsequently reposted.
The athlete in question was 28-year-old Kexin Fan, who in the GIF is seen reaching over the leg of another competitor to touch a puck, the marker used in the event.
Seconds later, the marker appeared to be flicked toward Canadian Alyson Charles, who then lost her balance and fell on the ice.
... Canadian skater Kim Boutin ultimately won Monday’s 500-meter race and advanced to the semifinal. Her teammate, Florence Brunelle, finished second but was disqualified for tripping both Charles and Fan, according to The Independent.
Charles was also allowed to advance since she was in second place before falling. She finished fourth in the semifinal, third in the B final and eighth overall, as per News.com.au.
Italy’s Arianna Fontana ultimately took home the gold during the final. The Netherlands’ Suzanne Schulting bagged silver, while Boutin took bronze.

I had to search a bit to find an article with the gif that had not yet been copyright-removed by the IOC.
