MotoGP confirmed Pramac Ducati rider Francesco Bagnaia will miss this weekend's Czech Republic Grand Prix and next weekend's race in Austria after sustaining a knee injury in a crash during free practice in Brno on Friday.
The Italian crashed at turn one and was taken to Brno University Hospital where it was confirmed the 23-year-old had a fracture that required surgery.
"The radiographs show a fracture in the tibia which will certainly have to be operated on," Pramac boss Francesco Guidotti said, adding that the rider would return to Italy.
"Now he is doing the magnetic resonance to see if there is involvement of the ligaments.
