British track cyclist Victoria Williamson has undergone surgery after suffering serious injuries in a crash while competing at the Rotterdam Six-Day on Saturday.
The 2013 team sprint World Championship bronze medallist sustained fractures to her pelvis and several vertebrae after colliding with Elis Ligtlee of the Netherlands in a sprint heat.
Williamson is to remain in hospital over the next few days and the 22-year-old faces a lengthy spell on the sidelines.
Great Britain Cycling Team sprint coach Justin Grace said: "Victoria is being very well looked after here in Rotterdam and the well-wishes people have been sending her are very much appreciated.
"She gave us all a scare last night and while her injuries are serious they are not life-threatening.
"From a performance point of view this is another injury to deal with - Victoria has a long road to recovery ahead of her but her health is the highest priority for the whole team and we'll make sure she receives the best possible care."
The crash brought Saturday's action to a premature end.
