Danilo Petrucci has undergone a three-hour operation on his right hand, injured during Friday's final day of official MotoGP testing at Phillip Island.
The Pramac Ducati star broke three metacarpals during a fast out-lap accident at Turn 8 (Hayshed) and has already been ruled out of the final pre-season test in Qatar.
However following the surgery, which took place in Melbourne, Petrucci pledged that he and his 'bionic hand' will be ready for the first race of the season at Qatar from March 17-20.
Petrucci - who like team-mate Scott Redding is using GP15-spec Desmosedici machinery - has been fastest on two of the six days of official MotoGP testing to date, once at Sepang and again on day one in Australia.
The Italian left the test 14th quickest after his early exit, but only 0.864s from the top.
