The injury is sufficient to mean Franco will miss this weekend’s event and he is undergoing medical assessment to determine the best course of action for recovery.
Morbidelli had been looking forward to Assen, after the global pandemic forced its cancellation last year, as it is somewhere that he has enjoyed success in the past. In 2017, when competing in Moto2, the Italian secured pole position, the race win and posted the fastest lap.
Franco currently sits 11th in the MotoGP World Championship with 40 points.
