Felipe Massa said Tuesday that he will leave Ferrari at the end of the Formula One season.
Massa used his Twitter account to post the announcement with a message on Instagram.
"From 2014 I will no longer be driving for Ferrari," Massa wrote. "I would like to thank the team for all the victories and incredible moments experienced together."
The 32-year-old Massa has made 184 starts for Ferrari, winning 11 races since joining in 2006 from Sauber.
All of the Brazilian's wins with Ferrari came during his first three seasons with the team. He hasn't won a race since a life-threatening accident at the Hungarian Grand Prix in 2009 and his contract is up at the end of this season.
"Right now I want to push as hard as possible with Ferrari for the remaining seven races," Massa said. "For next year, I want to find a team that can give me a competitive car to win many more races and challenge for the Championship which remains my greatest objective!"
Raikkonen, who drives for Lotus, has been linked with a return to Ferrari. He raced for Ferrari from 2007-2009, and his title in 2007 was the last time Ferrari won the driver's crown.
