OSKALOOSA, Iowa 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.
Stewart will need a second surgery and remains hospitalized. There was no timetable for his return.
Stewart-Haas racing named Max Papis as the substitute driver in the No. 14 for Sunday's NASCAR race at Watkins Glen. Papis has made 35 career Sprint Cup starts.
The injury means Stewart won't be able to race in a similar event at Plymouth Speedway on August 17th. It's still too early to tell whether Stewart will be able to make an appearance at Plymouth that night or at the Newton Center in Lakeville on August 16. Stewart traditionally appears for an autograph signing and question and answer session with fans at the Newton Center once a year to support the Little Hoosier 100 and his longtime friends, the Newton family.
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.
