Fiat Yamaha's Jorge Lorenzo will undergo medical checks in the morning after damaging his shoulder and bruising his foot in the second of two qualifying crashes at Laguna Seca's MotoGP round today.

The Spaniard spectactuarly lobbed it on cold tyres as he exited The Corskcrew with only a handful of minutes to go in qualifying practice - his second crash of the session.

“I was trying to push but first I had some traffic and then the tyres were cold, and I wasn’t in the right shape to try to improve my time. I’m disappointed for these two crashes but I am okay and I am optimistic that I will be able to ride tomorrow," said Lorenzo.

"Now the American doctors and the Clinica Mobile are working together to try to help me as best they can and make me more comfortable. Thanks to all the American people here for their support!”

Lorenzo will undergo medical checks before morning warm up to evaluate whether he is fit to race.
