Dario Franchitti has surgery in Indianapolis on broken right ankle

Three-time Indianapolis 500 winner Dario Franchitti has undergone another surgery on his broken right ankle.

It's the second operation on his ankle since Franchitti was injured in an Oct. 6 accident on the last lap of the Grand Prix of Houston. He also fractured two vertebrae and suffered a concussion.

IndyCar orthopedic consultant Dr. Terry Trammel said Monday's surgery lasted just over three hours and was to repair the talus bone in Franchitti's ankle. The talus bone connects the leg and the foot.

The surgery was performed by Dr. Tim Weber, who told Trammel the post-operation X-rays looked good.

Franchitti's accident occurred when contact with Takuma Sato sent his car sailing into the fence. Debris from accident injured 13 fans and one official.
