Dario Franchitti: IndyCar champion fractures spine in crash
Four-time IndyCar champion Dario Franchitti has fractured his spine in a crash at the Houston Grand Prix.
The 40-year-old Scot suffered multiple fractures including a broken ankle after crashing into the track wall.
His car flipped into the air following a final lap collision with Takuma Sato and at least 13 spectators were injured as debris flew over safety fencing.
Franchitti's team owner Chip Ganassi said: "His ankle and back are a little sore. He is going to be okay."
Three-time Indianapolis 500 winner Franchitti hit the back of Sato's car and was propelled into the air and against the fence. His car exploded into several pieces but did not catch fire.
Sato said: "On the last lap I caught the marbles (chunks of rubber that come off the tyres and lie on the track) and brushed the wall and lost momentum.
"A couple of cars passed me as I was offline and in turn five. I got very loose and Dario and I came together."
Race promoters said 11 spectators were treated at the track while two more were transferred to hospital for evaluation.
Franchitti's former team-mate Dan Wheldon, from England, died in a crash at the Las Vegas Indy 300 in October 2011.
Will Power, who won the Grand Prix, said the accident reminded him of the Las Vegas crash, where he and Wheldon both hit the fence.
"I just saw Dario's car and him sitting in it with a lot of damage, and yes, that's what it reminded me of," he said.
"I hate seeing that. We try to keep these cars on the ground."
Franchitti's team-mate Scott Dixon, who leads the overall standings, said: "The smells and the visuals, you have the remnants of Vegas popping into your head with you coming around the corner and you can't drive through it because there's a field of debris.
"There was nowhere near the amount of damage that we saw (in 2011), but seeing the replay was a big shock."
