A forerunning bobsled barreled into a worker Thursday, just before two-man bobsled training began during the Sochi Winter Olympics in Russia.
Three workers were walking on the track at the Sanki Sliding Center when a bobsled sped toward the finish line, the Chicago Tribune reported. Two of the workers were able to jump out of the way, but the sled collided with the third worker and flung him several feet.
The worker was rushed to the hospital by an ambulance and “has two broken legs,” International Olympic Committee Spokesman Mark Adams told The Associated Press.
"We still do not know why he was in this zone and exactly what happened," IOC President Thomas Bach told the AP.
Announcers are supposed to warn when there is a sled on the tracks, according to USA Today, but is unclear whether or not this announcement was made before Thursday's incident.
"The worker is undergoing surgery for two open fractures in his legs," Bach told USA Today.
The bobsled training session was delayed for a half hour while workers cleared the track from debris and repaired a light that was destroyed during the accident.
Though accidents with pedestrians and bobsleds are rare, there have been some in the past. One such incident in 2005 cost American skeleton racer Noelle Pikus-Pace the opportunity to compete in the 2006 Torino Olympics after an out of control bobsled broke her right leg, USA Today reported.
