INDIANAPOLIS Indianapolis Mayor Greg Ballard was hit in the arm by debris as he waved the flag to start the inaugural Grand Prix of Indianapolis this afternoon at Indianapolis Motor Speedway.
The unidentified object hit Ballard in the elbow while he held the green flag that symbolically starts the race, said mayoral spokesman Marc Lotter.
The medical staff looked over Ballard's arm and determined he was not seriously injured, Lotter said. According to Ballard's Twitter account, he left the track after being treated to watch the rest of the race from home.
Lotter did not know what struck the mayor.
The debris likely was caused by a crash at the start of the race, when pole-sitter Sebastian Saavedra's car was struck from behind by Carlos Munoz and then Mikhail Aleshin.
The crash scattered debris across the front straightaway.
