It emerged earlier on Tuesday that Honda will drop Dani Pedrosa at the end of 2018 after 13 seasons, with Lorenzo set to leave Ducati to replace him.

The decision to hand Petrucci a works ride was made personally by Ducati CEO Claudio Domenicali.

A two-year agreement for Petrucci to step up to the works team alongside Andrea Dovizioso was reached last weekend at Mugello – where Lorenzo secured his first victory as a Ducati rider.

The other contender to replace Lorenzo had been Petrucci's current teammate Jack Miller, who will instead remain at Pramac in 2019 alongside Moto2 championship leader Francesco Bagnaia.

Petrucci had a firm offer on the table for Aprilia, but that seat is now likely to go to Andrea Iannone, who confirmed ahead of the Mugello weekend he would be leaving Suzuki at the end of 2018.

After strongly hinting his tenure at Ducati was coming to an end after his Mugello win, Lorenzo subsequently clarified that the relationship between the two parties is “over”.

“I kept telling people inside the team to believe in me, to bring me what I asked for. They have done it, but too late," Lorenzo said.

"I have the impression that Gigi [Dall'Igna, technical boss], Paolo [Ciabatti, sporting director] and Davide [Tardozzi, team manager] wanted me to stay. But I do not hold a grudge.”

It is believed Lorenzo secured the Honda deal before Ducati made a final decision not to keep him, but he had also been working on a potential satellite Yamaha option in anticipation of losing his current ride.

The satellite Yamaha project could still go ahead, with Pedrosa now an option there.

Marc VDS had been expected to replace Tech 3 as Yamaha's satellite outfit next year, but question marks remain over its MotoGP future following Michael Bartholemy's acrimonious departure from the team.

Malaysian oil giant Petronas has been linked with taking over the vacated Marc VDS grid slots, but there is also the potential for it to link up with the Angel Nieto (formerly Aspar) team.
