OSKALOOSA, Iowa (AP) -- Three-time NASCAR champion Tony Stewart has broken his right leg and had surgery following a crash in a sprint car race at Southern Iowa Speedway Monday night.
A spokesman for Stewart said the 42-year-old driver broke his right tibia and fibula.
A scheduled test for the No. 14 Stewart-Haas Racing NASCAR team at Atlanta Motor Speedway on Tuesday was canceled. No replacement driver for this weekend's race at Watkins Glen was immediately announced.
The accident came a day after Stewart finished ninth in the NASCAR race at Pocono Raceway. He's 11th in the Sprint Cup standings with five races to go until the Chase for the championship field is set.
Stewart was leading the 30-lap feature in a 360 winged sprint car with five laps to go when a lapped car spun in Turn 4 and collected Stewart and two others.
