Swedish driver Kenny Brack, who was seriously injured in the Indy Racing League in 2003, will race in the Indianapolis 500 later this month.
Brack suffered serious injuries in a crash 18 months ago
Brack broke his back, sternum, ribs, right leg and both ankles in a crash during the season finale at Texas Motor Speedway in October 2003.
He will replace last year's Indy 500 winner Buddy Rice.
Rice suffered a back injury and concussion in a practice sesssion earlier this month.
"It is pretty weird that Buddy filled in for me last year and now I will fill in for him," said Brack.
Brack was the 1998 Indy Racing League champion and 1999 Indianapolis 500 winner. He will race the No. 15 Argent/Pioneer Honda car on 29 May.
