Kimi Raikkonen has undergone successful back surgery as planned on Thursday and is currently resting in hospital in France.
The Finnish driver chose to skip the final two races in order to schedule surgery sooner than previously planned, so not to impact on his preparations for 2014 with Ferrari.
A statement from Lotus read: “As planned, Kimi Räikkönen underwent back surgery yesterday at The University Hospital of Strasbourg. 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.”
Fellow Finn Heikki Kovalainen is currently filling in for Raikkonen.
