( CNN ) -- MotoGP world champion Jorge Lorenzo will be kept under observation in hospital after flying off his bike in a 200-kilometers an hour crash during a wet practice session at Assen Thursday . Lorenzo will miss Saturday 's race in the Netherlands after being caught out by standing water on the track and flying over his handlebars , eventually landing heavily on his left shoulder and fracturing his collarbone . The Spaniard , who won in Spain and Italy , came off during the second session of practice at Turn 13 . According to race organizers , Lorenzo will be flown to Barcelona for surgery late Saturday or early Sunday . Xavier Mir , the doctor who carried out the examination on Lorenzo , confirmed the rider would undergo scans and be kept in for observation . `` Jorge has suffered an accident at over 200 kilometers an hour and the obvious injury at this point is a broken left clavicle , '' he told the competition 's official website . `` However , as this was a significant accident , we have to take into account that there could also be head , thoracic or abdominal injuries . `` For now , we have taken him to hospital in Assen where CT scans will be carried out in those three areas to rule out any further injuries . `` It would also be a prudent move to observe him over 12 hours to make sure he can be treated by the appropriate parties when he arrives in Barcelona tomorrow ( Friday ) . '' Lorenzo had moved to within seven points of world championship leader Dani Pedrosa following his recent victories . But he will now have to watch from the sidelines at a venue where he failed to make it past the first corner last year .
