England cyclist Matt Walls has been released from hospital after he was involved in a crash in which both he and his bike flew into the crowd.
The 24-year-old Olympic champion has “stitches in his forehead, scrapes and bruises” but no major injuries, said Team England.
He was treated in the stands at Lee Valley VeloPark for 40 minutes.
The Isle of Man’s Matt Bostock and Canada’s Derek Gee were also taken to hospital for tests.
Spectators were also injured, with one taken away in a wheelchair.
The rest of the session was abandoned and spectators were asked to leave while Walls was having treatment.
A Team England statement said: “Following medical treatment in hospital, Matt Walls has been discharged with stitches in his forehead, scrapes and bruises but thankfully no major injuries.”
Walls later tweeted to thank people for their messages of support, adding: “I’ve somehow come away with no serious injures, just a few stitches and pretty banged up.
“I really hope everyone else involved is OK, including the spectators that may have been injured.”
The crash happened in the final lap of the men’s scratch race qualifying as eight riders collided on the track.
