Ducati rules out Stoner's MotoGP return

The Australian retired from the sport at the end of the 2012 season, but returned to competition with Honda in the Suzuka 8 Hours last year before becoming Ducati's test rider.

Stoner has tested the Italian bike this year, but has insisted he has no plans to return to racing, even as a wild-card entry.

Domenicali reckons Stoner is not missing the racing, and feels there is no chance the Australian will want to compete again in MotoGP.

"The Ducatista are crazy and dreaming is what we do best. Casey started his relationship with us as a test rider," Domenicali said on Tuesday, speaking on the 90s anniversary of Ducati.

"He is in an extraordinarily positive moment of his life, after having raced for a long time with outstanding results, showing his great talent, but also had some difficulties managing the pace of life under competition.

"Today he is in the maturity of his life and is very happy.

"I think I can rule out with some confidence that he will come back to racing in MotoGP."

No decision on Lorenzo's teammate

Ducati confirmed on Monday that Jorge Lorenzo will join the team from Yamaha from 2016, having signed a two-year contract with the Bologna squad.

Lorenzo's arrival means at least one of Ducati's current riders - Andrea Dovizioso or Andrea Iannone - will need to leave the team.

Domenicali said nothing has been decided yet, but admits it will not be an easy decision.

"I think it will be a fairly transparent process. Normally Gigi and the boys of the racing department carry out a thorough evaluation. I think both Andreas have a good chance.

"Both are proving to be competitive, so it will be a complicated choice which will leave us with some regrets, because both have contributed to the growth of this project. It's a shame we don't have three bikes.
