Ryan Briscoe originally won the pole but was disqualified for a technical infraction and sent to the back of the grid. The pole winner after this became Danica Patrick for her third (and final) IndyCar pole. Briscoe's weekend got significantly worse as he was involved in a fiery crash with Alex Barron on lap 20. Briscoe was taken by helicopter to a Chicago-area hospital with head and back pain, but was alert. He suffered a concussion, two broken collarbones, a bruised lung and contusions to his arms and legs. The accident resulted in a 16-minute red flag.
