INDIANAPOLIS (AP) - Reigning world champion Casey Stoner is being treated for a suspected fractured right ankle after crashing in qualifications Saturday at Indianapolis.
The Australian's motorcycle wobbled as it came through one of the turns on the 2.621-mile road course. Stoner went airborne over the handlebars and slid across the track. After trying to stand up, he pointed at his injured leg and was taken away on a stretcher.
Originally, series officials thought Stoner injured his left ankle.
Last year, Stoner won the Indianapolis race after claiming the pole and was the favorite to take his second straight pole at Indy on Saturday.
He had posted the fastest lap early in qualifications, 1:39.465, but is fourth on the tentative starting grid with 15 minutes left in qualifying.
Also, Hector Faubel of Spain flew off his bike during qualifying for the Moto3 race. A spokeswoman for the Bankia Aspar team said the rider went to the hospital with bruised ribs and injured back.
Hector Barbera, who crashed during a Moto GP practice Friday and broke a vertebra, will head home to Spain for more tests. Toni Elias, the 2010 Indianapolis Moto2 winner, will replace him in the race on Sunday.
