Toni Elias grabbed a further hold on the Moto2 championship by winning his third straight race at Indianapolis.
The Gresini Moriwaki rider despite suffering from a bad case of the flu was able to prevail again in a red flagged and shortened race.
The first start had to red flagged due to two separate multi pile-ups at Turn 2, with Lukas Pesek (who started the cannonball incident) Gabor Talmacsi, Simone Corsi and Michael Ranseder all going down and in the second, which included Yonny Hernandez, RogerLee Hayden, Shoya Tomizawa and Vladimir Ivanov.
The race was shortened to 17 laps with Ranseder and Tomizawa unable to return to action in the restart, while Simone Corsi was pushed back to the last place on the grid for being late.
In the restart Elias got the hole shot while pole man Julian Simon dropped to fourth behind Anthony West and Scott Redding.
Simon got past Redding on the third lap and then set his sights on West and got past him and then overtook Elias on lap four, while the back of the field was another crash fest.
Ivanov took out Debon, Faubel binned his Suter while he was running in fifth with a trail of gas spilling out and catching fire on the asphalt.
Bradl went down after tangling with Cluzel and the three front runners started distancing the rest of the group.
