Ferrari mechanic on the mend after surgery following Bahrain Grand Prix accident

A Ferrari mechanic who suffered a broken leg after being hit by Kimi Raikkonen's car at the Bahrain Grand Prix was recovering after surgery on Monday.

Francesco Cigarini posted a picture on Instagram of himself lying in a hospital bed giving a thumbs up gesture and with a plaster cast on the leg.

The Italian later posted another of him standing on crutches.

"Surgery OK. I have to thank all the people worried for me. Nothing else, just a big thanks," he said.

Cigarini fractured the shinbone and fibula on his left leg after being struck during a botched pit-stop, with Ferrari driver Raikkonen given the signal to go before the left rear tyre had been replaced.

Raikkonen halted immediately in the pit lane and retired from the race while Ferrari team members tended to their stricken colleague. Sebastian Vettel went on to win for the Italian team.

The FIA later fined Ferrari $A85,000 for the incident.
