Indy Racing League veteran Eliseo Salazar underwent successful emergency surgery to repair a torn vertebral artery in his chest following a testing accident at Indianapolis Motor Speedway on Tuesday.

Dr John Fehernbacher, a vascular surgeon, performed the operation after the Chilean was taken to Indianapolis Methodist hospital from IMS for further evaluation. He was awake at the time of the transfer, but doctors decided to operate after discovering the torn artery during his check-up.

Salazar is listed in stable condition in the critical care unit at the hospital, according to Dr Henry Bock, medical services director for the Indy Racing League.

The former F1 and CART driver is naturally a non-starter for this weekend's IRL event at Nazareth Speedway, but no replacement has yet been named by his AJ Foyt Enterprises team. The team has already replaced Donnie Beechler with Airton Dare this season, after the American suffered a concussion inpractice for round one.
