Diehard sports fans are accustomed to witnessing mishaps during the course of competition. Some accidents are freak while some occur due to an error in judgement or carelessness.
Check out what happens when sport stars collide, crash and fall.
From tennis ace Serena Williams to FDJ rider William Bonnet of France to Honda Moto3 rider Efren Vazquez, here are some bone-chilling moments captured on camera.
Wimbledon champion Serena Williams slips during a women's singles match. At 33 years and 289 days, she is now in her own exclusive club as the oldest player in the professional era to clinch a Grand Slam title, surpassing Martina Navratilova by 26 days.
What makes her tally of 21 Grand Slam titles so remarkable is that eight have come after she turned 30, with no sign that her ability to pummel much younger opponents is on the wane. Photograph: Suzanne Plunkett/Reuters

Chile's Eduardo Vargas gets a kick in the face from Argentina's Nicolas Otamendi during their Copa America 2015 final, in Santiago, Chile.
Chile won the Copa America for the first time when a cheeky penalty from Alexis Sanchez clinched a shoot-out victory over Argentina and glory for the host nation's golden generation in front of their own fans.
