Ducati has confirmed Enea Bastianini will miss the upcoming Americas GP due to the shoulder injury he suffered in Portugal.
The Italian sustained the injury in the first sprint race of the year from Portimao and was subsequently ruled out of the remainder of the round, as well as the following event in Argentina.
Bastianini was battling Luca Marini before the collision put them both out of the race.
Ducati put the 25-year-old through a test at Misano with the Panigale V4S but a following check-up determined that he needed more time to recover.
The team says that it hopes to get Bastianini back on his bike for the fourth round from Jerez at the end of the month.
Bastianini will be replaced at the Circuit of the Americas this weekend by Michele Pirro.
A full statement from the team reads: “After completing a few laps at Misano with the Panigale V4S, the Ducati Lenovo Team rider underwent a further check-up in Forlì at Dr Porcellini’s clinic, who confirmed that Bastianini will still need a few more weeks to fully recover from the right shoulder injury sustained in the Portuguese GP.
“Enea will therefore continue his rehabilitation with the aim of returning to the track in Jerez and will be replaced in Texas by Michele Pirro.”
Pirro competed at three rounds last year with Ducati.
Bastianini is not the only driver that has been ruled out of the upcoming race weekend.
Marc Marquez announced on social media that he would not be taking part in the event from Texas this weekend as he is still recovering from injury.
