Lotus have confirmed that driver Kimi Raikkonen has come through successful back surgery at the University Hospital of Strasbourg.
The 34-year-old was ruled out of the final two races of the season due to the discomfort he had been suffering over the last few weeks.
On the Formula 1 team's official Twitter page, they said: "Lotus F1 Team is happy to report that the operation was totally successful, according to Professor Afshin Gangi.
"Kimi will now rest for a few days and he will start his recovery process as early as next week. Everyone at the track and at Enstone wishes him a quick recovery."
Raikkonen will return to Ferrari to team up with Fernando Alonso for the 2014 campaign.
