Dario Franchitti has announced that he will no longer be competing in motor racing, saying that he is retiring on the advice of the doctors treating him for injuries that he sustained in a late-race accident in Houston last month.
"Since my racing accident in Houston, I have been in the expert care of some of the leading doctors and nurses, all of whom have made my health, my safety and my recovery their top priority," said Franchitti in a statement released by the Chip Ganassi Racing Team on Thursday.
"One month removed from the crash and based upon the expert advice of the doctors who have treated and assessed my head and spinal injuries post-accident, it is their best medical opinion that I must stop racing," he confirmed.
"They have made it very clear that the risks involved in further racing are too great and could be detrimental to my long term well-being," added Franchitti. "Based on this medical advice, I have no choice but to stop.
"I am eternally grateful for the medical care I have received over the last several weeks," he continued. "I'd also like to thank my family and friends for their unbelievable support.
"I'd like to thank all my fellow competitors, teammates, crew and sponsors for their incredible support over the course of this amazing ride," said Franchitti. "Racing has been my life for over 30 years and it's really tough to think that the driving side is now over.
"I was really looking forward to the 2014 season with Target Chip Ganassi Racing, with a goal of winning a fourth Indianapolis 500 and a fifth IndyCar Series championship," said the 40-year-old, originally from Bathgate in Scotland. He had been due to be joined at the team next year by his old friend Tony Kanaan, as well as by longtime team mate Scott Dixon who just successfully clinched this year's IndyCar Series championship.
"I would be remiss if I didn't thank all my fans around the world. I can't thank you enough for standing by my side for all these years," Franchitti added. "I'll forever look back on my time racing in CART and the IndyCar Series with fond memories and the relationships I've forged in the sport will last a lifetime."
