Former Formula One driver and twice Champ Car champion Alex Zanardi will remain in an induced coma until at least next week, according to the neurosurgeon who operated on him.
The 53-year-old Italian suffered severe head injuries in a road accident while racing his handbike in Italy on Friday.
"Zanardi is in stable condition and the parameters are stable too," professor Giuseppe Oliveri told Sky in Italy. "This is what we can expect at best at the moment.
"It will take a long time. He will remain sedated for another 10-15 days. At present, his response is good.
