Kimi Raikkonen's back surgery has gone ahead as planned and been a complete success, according to a statement released by the Lotus F1 team.

"As planned, Kimi R?ikk?nen underwent back surgery yesterday at The University Hospital of Strasbourg," read the statement issued shortly before 4pm GMT on Friday.

"Lotus F1 Team is happy to report that the operation was totally successful, according to Professor Afshin Gangi," the statement added. "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."

After it emerged last weekend that Raikkonen had elected to schedule surgery for this week and miss the final two races of the season with Lotus, Raikkonen has been replaced for the US and Brazilian Grand Prix races by fellow Finn Heikki Kovalainen.

The sides of both Lotus cars are sporting a new hashtag slogan, #GetWellSoonKimi as they compete in this weekend's race at the Circuit of the Americas in Austin, Texas.

Fernando Alonso - who will be Raikkonen's team mate at Ferrari next season - has been passed fit to race this weekend after suffering from back pain of his own following an incident at Abu Dhabi in which he was forced to run wide over some aggressive kerbing in a racing incident with Jean-Eric Vergne.

Alonso was photographed secured to a back board as a precaution after the race ended and he was dispatched to hospital for further checks, but Ferrari insisted there was nothing untoward with the Spaniard's condition and that they weren't worried about any long-term problems for their star driver.
