Britains Katy Marchant suffered a suspected broken arm and the UCI Track Champions Leagues final round was cancelled following a nasty crash at the Lee Valley VeloPark on Saturday night.
Marchant, who won team gold in the womens sprint at the summer Olympics in Paris, was catapulted over a barrier and landed in the crowd after a collision with German rider Alessa-Catriona Pröpster.
A medical team treated Marchant for half an hour before she was taken to hospital. Four spectators were also reported to have been injured at the London 2012 venue in Stratford.
Propster was on the inside of Marchant in the first round of the womens keirin when she moved high up the track and collided with the British rider at force, propelling the pair over the barriers.
Pröpster also required medical attention, with television cameras breaking away from the incident and the crowd falling silent before racing was abandoned and fans were asked to leave.
Adam Blythe, the former British cyclist, said on Eurosport: Ive got people up there that have given me the feedback and Ive heard from a couple of her team-mates as well that Katy Marchant is all OK.
Just a broken forearm and its a little bit of a shock. There were a couple of members from the crowd that were involved and they seem to be OK as well. Everyones in a good condition, although Katy has broken her forearm.
The racing has been cancelled for the night due to that crash, so a disappointment, but the good news and the main thing is that everyone is OK and in a good condition. Enough to get up and walk home tonight.
British Cycling said in a statement: We can confirm that two riders and four spectators received medical treatment following an incident during tonights UCI Track Champions League event at Lee Valley VeloPark in London.
The incident took place during the womens keirin race. The event medics responded immediately, with one rider transferred to the hospital.
WBD Sports [the broadcaster], British Cycling, Lee Valley VeloPark and the Union Cycliste Internationale unanimously decided to suspend all further racing for the evening and want to extend their best wishes for a speedy recovery to both riders and all affected spectators.
We wish to thank the medical staff for their prompt response and ongoing support. We are working closely with all parties to review the incident before taking appropriate action. No further comments will be made at this time.
The crash echoed the incident at the Commonwealth Games in 2022 when Olympic champion Matt Walls was one of three riders hospitalised following a horrorific crash.
Walls, who won omnium gold at Tokyo 2021, was sent flying over the barriers and into the crowd at the London 2012 velodrome as he tried to take evasive action to avoid a pile-up ahead of him.
A number of spectators including a small girl were hurt in the dramatic incident, leading Dame Laura Kenny, the five-time Olympic champion, to call for bigger barriers or screens to be fitted in velodromes.
Maybe there should be screens because Matt should not have been able to go over the top and into the crowd, thats pretty damn dangerous, Kenny said at the time. Its the third time now Ive been in a velodrome and witnessed someone go over the top.
