Oxfordshire's Bradley Smith is out of Sunday's Moto2 race in Malaysia after suffering a broken left collar-bone and bruising to his chest.
The 20-year-old, from Forest Hill, near Oxford, crashed on the first lap of practice at Sepang.
It came following a freak burst of rain, which caused Jules Cluzel, Marc Marquez and Smith to collide at turn 10.
He was taken to hospital in Kuala Lumpur for a scan and was asked to stay overnight.
