Cal Crutchlow has been officially confirmed as a factory Ducati MotoGP rider for the next two years.
News of the deal was leaked on Thursday
, with the Italian manufacturer confirming on Friday that the 27-year-old has signed a two-year deal to ride alongside Andrea Dovizioso.
In a short statement, Ducati said the pair would work together on 'developing the Desmosedici and growing Ducati's MotoGP project'.
The Englishman, with Yamaha since his title winning 2009 World Supersport season, will take the place of Nicky Hayden.
Crutchlow, who has raced for the Monster Yamaha Tech 3 team since his 2011 grand prix debut, is enjoying his best season in MotoGP - holding fifth in the standings, as the leading satellite rider, with four podiums and one pole position.
Current Ducati pair Dovizioso and Hayden sit seventh and ninth in the 2013 world championship standings, without a podium. Ducati's most recent race victory was with Casey Stoner in 2010.
Crutchlow's place at Tech 3 will be taken by Moto2 star Pol Espargaro
, who has inked a two-year deal with Yamaha.
Espargaro will team up with Bradley Smith in a line-up the French team said shows its 'commitment to developing and nurturing fast talent in MotoGP'.
