Jorge Lorenzo breaks collarbone in Assen fall
AMSTERDAM -- Defending MotoGP champion Jorge Lorenzo broke his left collarbone Thursday in a high-speed crash on a rain-slicked track during practice before the Iveco TT in Assen.
Lorenzo, currently second in the standings behind fellow Spaniard Dani Pedrosa, lost control of his Yamaha in afternoon training and was thrown off the motorbike on the Hoge Heide straight.
He slid on his back along the soaked track before coming to a standstill on grass. He got up and gingerly held his left arm before being driven away in an ambulance.
Race organizers said he would fly to Barcelona and undergo surgery there Friday.
The injury hampers Lorenzo's hopes of retaining his title after he put himself in contention by winning three of the last six races.
