ENGLAND track cyclist Matt Walls was involved in a horror crash at the Commonwealth Games this morning when he was catapulted over the barriers and into the spectators at London’s Lee Valley.

The 24-year-old Olympic omnium champion received treatment for more than 40 minutes before being taken away by ambulance, with spectators also hurt after he and his bike had come over the top of the barriers on the high corner banking.

Witnesses said that because of the gradient of the banking, spectators in the front row had been unsighted for the crash. One man received treatment for cuts to his arm and a young girl also received minor attention.

Walls had been trying to avoid riders who had fallen in an incident that began on the entrance to the corner. The stricken pair of New Zealander George Jackson and Australia’s Josh Duffy were sliding up the banking, forcing Walls up on to the barrier and then over it.

Canadian Derek Gee also surfed the top of the barrier but managed to avoid following Walls in the stands.

The Isle of Man’s Matt Bostock was also taken to hospital with head and shoulder injuries while Canadian Mathias Guillemette was disqualified for causing the initial crash.

The remainder of the morning session at the velodrome was cancelled and spectators were asked to leave as medical staff attended to Walls.

Saturday night’s session was also marred by injury: Jack Carlin won men’s keirin silver for Scotland — but only after seeing his former housemate Joe Truman knocked unconscious in a frightening high-speed crash.

England’s Truman had nowhere to go when Australian Matthew Glaetzer touched wheels with Carlin in the second round of the event, with Glaetzer falling in front of Truman, who went straight over the top and hit his head.

The 24-year-old initially lay motionless on the infield of the velodrome as medical staff rushed to his aid and was helped away in a wheelchair, receiving oxygen. He was then transferred to hospital with a suspected broken collarbone.
