Valentino Rossi will leave Yamaha at the end of the 2010 season. He won't be moving to automobile racing, as some have speculated, but will join the Ducati Corsa MotoGP team.

Motorcycle News UK and other European press are reporting that a MotoGP insider has confirmed that Rossi and Yamaha have failed to resolve a contract dispute; as well, Rossi refuses to continue teaming with Jorge Lorenzo.

According to MCN, a "senior MotoGP figure" said, "I know for sure that Rossi will go to Ducati next season. The deal has been done."

Details of the Ducati signing are said to be revealed at this weekend's MotoGP round at Catalunya.
