Nicky Hayden out of Indianapolis race
American Nicky Hayden won't race on Sunday at Indianapolis after doctors declared him "unfit to ride" on Saturday night.
The announcement came hours after Hayden sustained a concussion during a hard crash in qualifying.
Hayden regained consciousness before being placed on a stretcher and into an ambulance. He was taken to Methodist Hospital for a CT scan and an X-ray on his right hand.
The Kentucky native and 2006 world champ crashed between turns 14 and 15 on Indy's 16-turn road course.
When the No 69 bike spun sideways , Hayden was flung into the air and hit his head on the asphalt surface hard before somersaulting across the track.
The Ducati team has not said anything about a replacement rider.
Hayden had qualified eighth for the Indianapolis Grand Prix.
