Twelve of a 21-strong field crashed in a nasty sequence of events at the Brisbane World Cup track cycling round on Sunday.
The Omnium scratch race left three cyclists – France’s Clara Copponi, Japan’s Kie Furuyama and Kazakhstan’s Rinata Sultanova – unable to contest the other three events on the night.

Two laps remained when the collision occurred, sending bodies flying down the banking at Anna Meares Velodrome.
Riders were ridden over by others who could not avoid the havoc, with a number of the competitors receiving attention at the bottom of the track.
Australia’s Annette Edmondson avoided the incident but was unable to avoid disaster in the 20km points race, needing to be stretchered off the the track.
Her crash cruelly denied the 27-year-old, sitting second in the overall Omnium standings at the time of the incident, the chance of a third gold medal at the three-day meet.
She fell heavily sitting in second spot midway through the four-event’s finale.
Medical staff later cleared Edmondson of serious injury.
She finished 17th overall in the Omnium, won by American Jennifer Valente.
Her crash momentarily took the wind out of the Australian team, which won the round and celebrated Sam Welsford and Cameron Meyer’s Madison gold on Sunday.
Edmondson was one of the stars of the meet by helping Australia win team pursuit and Madison gold.
