FONTANA, Calif. -- Justin Wilson said he "was not where I needed to be on the angle of the exit" of Turn 2, which resulted in the No. 19 Dale Coyne Racing car making a 360-degree spin and being struck by the swiftly approaching car of Tristan Vautier on Lap 111 of the MAVTV 500 on Oct. 19 at Auto Club Speedway.

Wilson, 34, was transported by ground to Arrowhead Regional Medical Center for evaluation, which revealed three non-operable pelvic fractures and a small pulmonary contusion. Wilson was kept overnight for further observation, according to INDYCAR medical director Dr. Michael Olinger, and will return to his Colorado home early this week for rehabilitation.

After the slow spin, the car slid up the racetrack, and with its nose pointed toward the outside wall, was struck by the No. 55 Schmidt Peterson Motorsports car driven by Vautier on the front-right side. The Holmatro Safety Team was quickly on the scene to attend to both drivers.

“It just wiggled and I tried to catch it but it just came around,” Wilson said Oct. 20. “I was not where I needed to be on the angle of the exit and if you get that wrong then the aerodynamics and the track seams can really get you and they certainly did.”

Said Vautier, who was checked at the infield care center and released: "There was a cloud of smoke and I didn't see (Wilson)."

Team owner Dale Coyne visited Wilson, who finished sixth in the IZOD IndyCar Series standings, in the hospital.

“Justin is in good spirits," he said. “The doctors say he will be six to eight weeks of non-load bearing on his right leg before he can start rehab. Knowing Justin, he will be back on his mountain bike before you know it.”

Josef Newgarden, running closely behind the incident in the No. 67 Sarah Fisher Hartman Racing car, moved to the high side in an attempt to slide past Wilson's car but pinned the No. 4 National Guard Panther Racing car driven by Oriol Servia against the SAFER Barrier.

Both drivers also were checked at the infield care center and released.

James Jakes' No. 16 Acorn Stairlifts car for Rahal Letterman Lanigan Racing was struck by debris and slid into the SAFER Barrier. He also was checked at the infield care center and released.
