Australian cyclist Melissa Hoskins has been taken to hospital following a crash involving the country's team pursuit squad at Rio 2016.
The quintet of Hoskins, Ashlee Ankudinoff, Georgia Baker, Amy Cure and Annette Edmondson were preparing for their event, which gets under way on Thursday, when four of the riders came off at race speed.
"The women's team pursuit crashed during training today on the Rio Olympic Velodrome," read a statement from the Australian Olympic Committee.
"The five-woman team of Ashlee Ankudinoff, Georgia Baker, Amy Cure, Annette Edmondson and Melissa Hoskins were doing a training effort at race speed when the crash happened.
"Edmondson was leading the team into turn three at the end of the back straight and she stayed on her bike but her four team-mates did not.
"Ankudinoff, Baker and Cure walked off the track and are being treated for track friction burns and bruises. Hoskins was stretchered off the track as a precaution and has been taken to hospital for assessment.
"An update on her condition will be provided when available."
