Tony Stewart will not compete in this weekend's Sprint Cup Series race at Watkins Glen International after undergoing surgery for a broken leg.

Stewart, a three-time Sprint Cup champion, broke his right tibia and fibula when he was involved in a multi-car accident during a sprint car race on Monday night at Southern Iowa Speedway, a half-mile dirt track. He was alert and conscious when he was placed on a stretcher and taken by ambulance to a nearby hospital. He immediately underwent surgery.
