Italy's MotoGP world champion and standings leader Francesco Bagnaia was involved in a nasty crash at the start of the Catalan Grand Prix on Sunday.
The Ducati factory rider, who started in pole position, lost control after the second bend, was thrown over the handlebars in front of the chasing pack and his leg was hit by the KTM of Brad Binder.
The race was halted and an ambulance arrived to take Bagnaia to the circuit's medical centre.
"Pecco (Bagnaia) has had severe polytrauma, a motorbike ran over him in the femoral and tibial area," MotoGP Medical Director Dr.
Angel Charte told Dazn.
"We have taken x-rays of this area and have detected a small injury that we don't know if is current or old.
"We need to do an urgent CAT scan and that is why we have sent him to the general hospital.
"At cranial, thoracic and abdominal levels, he has been normal at all times.
"He was conscious and oriented.
"The image we have seen is from conventional radiology, so it is difficult to be sure that there is no fracture.
"It is necessary to do a CAT scan".
