Italian rider Marco Simoncelli has died after a horrific crash at the Malaysian MotoGP in Sepang. The race was stopped on lap two when Simoncelli's bike veered across the track at turn 11 into the path of Colin Edwards and Valentino Rossi.
The 24-year-old had his helmet knocked off and was hit by both other riders. American rider Edwards also fell and dislocated his shoulder - while Simoncelli's fellow Italian Rossi was able to return to the pits.
Simoncelli lay motionless on the track after the impact, while the race was immediately red-flagged.
Medical director Michele Macchiagodena said Simoncelli suffered a "very serious trauma to the head, to the neck and the chest".
