Nov.15 (GMM) Kimi Raikkonen is now recovering from successful back surgery, according to Finland's MTV Sport.

After suffering with severe pain from an old back injury at Grands Prix recently, the Finn elected to sit out the last two races of 2013 in order to have the operation well ahead of his 2014 switch to Ferrari.

The surgery, performed on Thursday, "went well", MTV reported, and the 34-year-old "can start light exercise in 4 to 6 weeks".

For the last two races of 2013 in Austin and Brazil, Lotus replaced Raikkonen with his Finnish countryman Heikki Kovalainen.
