Paralympian Alex Zanardi is in "very serious" condition following an accident during a handbike race near Pienza, Italy, on Friday.
According to the Associated Press (h/t USA Today), Santa Maria alle Scotte Hospital in Siena, Italy, said Zanardi underwent "a delicate neurosurgery operation" because of "severe cranial trauma."
Zanardi's coach, Mario Valentini, described the circumstances that led up to the accident: "It happened on a slightly downhill straightaway just before a slight curve in the road. Alex veered slightly into the oncoming lane just when a truck came. [The truck] tried to swerve but couldn't avoid the crash.
