Update: May 19, 2017: Despite initial reports, it appears that while Hayden did suffer a serious head injury, it’s unclear whether he was in a coma. The first paragraph has been updated to reflect this. The original text of this article continues below.
An update on his condition from RedBull reads:
“Nicky Hayden’s clinical condition remains extremely critical.
The young man, who is still in the intensive care unit of Cesena’s Bufalini hospital, has suffered a serious polytrauma with subsequent serious cerebral damage.
The prognosis remains reserved.”
He is being treated at the Maurizio Bufalini Hospital in Cesena, Italy.
Hayden was in Italy for the FIM Superbike World Championship. He was training on a bicycle along the Rimini coastline when he was hit.
