Jack Miller will leave Honda and join Pramac Ducati for the 2018 MotoGP season, it has been confirmed.

Miller will partner Danilo Petrucci next year, having signed directly with Ducati.

Crash.net reports the Australian will most probably have to make use of a year-old bike, while Petrucci gets the latest Desmsosedici machinery.

Miller made the move after HRC decided not to renew his contract. He could have remained at Marc VDS by signing directly for the team, but that would effectively have been a step down.

Miller opted to join Ducati instead, where he will take the place of Scott Redding, whose future is still unknown.

By only signing a one-year deal, Miller will be available to vie for a factory MotoGP ride when all of the official seats come up for renewal at the end of next year.
