Italian former Formula One driver and Paralympic champion Alex Zanardi was returning to intensive care on Friday, three days after being moved to a specialist recovery centre to treat serious head injuries.
The 53-year-old underwent three operations at Siena's Santa Maria alle Scotte hospital after being placed in an induced coma after the June 19 accident while taking part in a road race on a handbike.
He was moved last Tuesday to the Villa Beretta centre in northern Italy, but they issued a statement on Friday saying his condition was unstable and they were arranging a transfer to Milan's San Raffaele hospital.
The San Raffaele press office said Zanardi had yet to arrive.
A double Champ Car champion in the US, Zanardi had to have both of his legs amputated above the knee after a horrific crash in a race in Germany in September 2001.
He recovered to return to the track in touring cars before later taking up paracycling and winning four Paralympic gold medals.
