ROME (AP) — Race car driver turned Paralympic champion Alex Zanardi is undergoing head trauma surgery after crashing his handbike.
Zanardi was transported by helicopter to a hospital in Siena following a road crash near the Tuscan town of Pienza during a national race for Paralympic athletes on handbikes.
A medical bulletin from the hospital says Zanardi's condition is "very serious" due to "severe cranial trauma."
Zanardi won four gold medals in handbike at the 2012 and 2016 Paralympics.
The 53-year-old Zanardi had both of his legs amputated following a horrific crash during a 2001 CART race in Germany. He was a two-time CART champion.
