A track worker at the Sochi Winter Olympics has been airlifted to hospital after being struck by a forerunner during Thursday's training session for the two-man bobsleigh.
The incident took place towards the end of the course at the Sanki Sliding Center, with the worker taken by air ambulance to hospital.
A forerunner is a manned bobsleigh which runs down the track before the competitors begin their official training runs.
The extent of the worker's injuries are unknown, while bobsleigh training was delayed by the accident.
An IOC statement revealed that the worker had sustained two broken legs but was conscious and talking on arrival at the hospital.
